This study investigates the dynamics of strato-rotational instability (SRI) in a stratified, rotating fluid, focusing on the interaction between axial modes and spiral components. Through numerical analysis, we find that SRI induces oscillatory behaviours that change the mean flow, leading to the selective activation of distinct axial wavenumbers associated with upward and downward propagating spiral modes. These results suggest wave–mean flow interactions. The use of Radon transforms (RTs) allowed us to separate these spiral components, showing that each upward and downward component was individually modulated, but out of phase with each other. Inspired by the RT findings, a simplified toy model was developed to interpret the spiral pattern changes linked to amplitude modulations. The model considers two wave-like spirals propagating in opposite axial directions, linearly interacting. By incorporating out-of-phase individual spiral modulations, the model reproduces the observed spiral pattern transitions, offering a straightforward interpretation of the underlying physical processes. To explore the mechanism of individual spiral modulations, we consider a quasi-biennial oscillation (QBO)-like framework derived from the Navier–Stokes aligns in a rotating frame. These findings contribute to a better understanding of low-frequency SRI dynamics and may offer insights into similar phenomena in geophysical and astrophysical contexts.

Lipid accumulation in green microalgae is induced by stresses (e.g. nitrogen starvation) which compromise photosynthetic activity resulting in significantly lower biomass productivity than under nutrient replete conditions. While algae photosynthetic growth has been well characterized and modelled under nutrient replete conditions, the loss of photosynthetic activity during nitrogen starvation lacks specific studies to determine suitable parameterisation. The loss of photosynthetic activity of the lipid-accumulating microalgae Chlorella vulgaris NIES 227 was studied under varying light intensities during nitrogen starvation. Partition of assimilated carbon between the different macromolecules pools (carbohydrates, lipids, and proteins) was concomitantly monitored. The results showed that the decrease of photosynthetic activity correlated well to the increase of cell C:N ratio $(R^2$ = 0,883, $N$=65) enabling to develop a model of microalgae growth and carbon partition under nitrogen starvation. Biomass dry-weight increase could be predicted with good accuracy ($R^2$ = 0,940, $N$ = 66), as total lipid and carbohydrate production could also be predicted with fair accuracy ($R^2$=0,841 and 0,618 respectively). The present study henceforth showed that modelling microalgae productivity based on photosynthetic activity inferred from local light intensity, as done in scalable models under nutrient replete conditions, may be extended to nitrogen starvation conditions and enabled the prediction of lipids and carbohydrates productivity. The model proposed should thus prove useful in optimizing photobioreactors design for the production of important energetic molecules based on light distribution knowledge.

This work presents Large-Eddy Simulations of a three-dimensional airblast-type injector using a diffuse-interface Multi-Fluid approach. A four-equation model is employed, including a consistent phase transition solver and a thermodynamic closure suitable for evaporating and reacting flows. The influence of evaporation and combustion on the spray and flow dynamics is investigated through a comparative analysis of cold, evaporative, and reactive configurations. The method is first validated against reference results and known behavior for similar injector geometries. It is shown that the addition of evaporation significantly alters the liquid fuel distribution, particularly in the inner recirculation zone, while combustion further modifies both liquid and gaseous fuel fields due to temperatureinduced evaporation and fuel consumption. The reacting case exhibits typical flame features, including hollow cone structures and localized high-temperature zones near stoichiometric mixture fractions. These phenomena align well with expected flame behavior under airblast conditions. Phase transition and combustion also have a notable impact on the velocity field, with increased expansion and stronger recirculation induced by heat release. The proposed model captures these effects in a unified framework. Finally, the present multi-physics approach enables consistent and efficient simulation of multiphase, reactive sprays, providing physical insight into the coupled interaction between atomization, evaporation, and combustion. The method shows good numerical performance on the 3D injector, with a reduced computational time of 2.1 × 10 -5 s.mpi/node/it, which has no overcost compared to the Lagrangian reference model. The fully explicit treatment of the equation of state (NASG) ensures excellent robustness on complex geometries, while avoiding the iterative procedure required by cubic-type EoS. These numerical properties make the DIM suitable for industrial LES configurations involving evaporation and combustion, and further model development.

The growing interest in hydrogen as an alternative energy vector has raised new technological challenges, in particular regarding its storage. This has motivated increasing attention to ammonia as a hydrogen carrier. In parallel, the use of hydrogen-ammonia blends as combustible fuels has attracted significant interest, as such mixtures can be easier to handle in some applications than pure hydrogen, while still enabling carbon-free combustion.In this context, the present study focuses on modeling the ignition of arbitrary gaseous hydrogen-ammonia-air blends. First, the minimal chemical description required to accurately capture the ignition delay of these mixtures is identified, revealing three main ignition regimes. Ignition delay formulas are then derived for these regimes by extending methods previously developed for pure hydrogen and syngas. The resulting ignition time expressions are subsequently combined into a unified formulation, valid across a wide range of pressures, temperatures, and fuel compositions. Finally, modifications to a recently published passive scalar model for CFD tools are introduced so as to accurately predict ignition events in hydrogen-ammonia-air mixtures while reducing computational cost.

The management of organic waste is currently a crucial environmental and societal challenge. Integrating waste treatment with renewable energy production has emerged as promising strategy for reducing the carbon footprint within an energy decarbonization approach. In this context, hydrogen-based biorefineries have gained attention for their ability to convert organic waste into carbon-free energy source. Nevertheless, their large-scale application remains constrained by limited yields, mainly attributed to the synthesis of volatile fatty acids (VFAs) as metabolic by-products. This review focuses on coupling hydrogen (H2) production with polyhydroxyalkanoates (PHAs) production to enhance organic matter recovery and support bioeconomy implementation. A comprehensive description of the coupled process design constitutes the first component of this review, emphasizing the interdependence of feedstock, inoculum types and bioreactor configurations at each stage. Various organic wastes are demonstrated as effective substrates for dark fermentation while the VFAs produced during this stage serve as potential carbon source for PHAs production. The review critically discusses key optimization strategies for the H2/PHAs coupled process, including pretreatment methods application, transition phase management and operational parameters control. It also highlights viable coupling strategies resulting in higher carbon removal efficiency. Based on different life cycle and techno-economic analyses, different challenges in feedstock pretreatment, process efficiency and downstream processing are identified. To overcome these constraints, several perspectives are suggested, emphasizing the relevance of incorporating modelling, nanotechnology and genetic engineering approaches, for better monitoring the coupled process, enhancing its efficiency and thus improving its sustainability and economic feasibility for large-scale implementation.

This article develops two algorithms for the thermal Lattice Boltzmann Method (LBM) to simulate supercritical fluid dynamics using real-fluid thermodynamics. The first algorithm employs a compressible formulation (LBM-C), while the second is based on a Low Mach Number approximation (LBM-LMN) to enhance computational efficiency without compromising physical fidelity. Both approaches use a conservative scheme compatible with cubic equations of state (EOS), enabling accurate representation of non-ideal behaviors under supercritical conditions and ensuring mass, momentum, and energy conservation. Validation on canonical supercritical flow benchmarks demonstrates that the LBM-LMN approach achieves accuracy comparable to the compressible formulation while reducing the overall computational time by a factor of about 15, as quantified by the RTTS parameter.
