Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
The Canadian Journal of Chemical Engineering, EarlyView.This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Energy Science &Engineering, EarlyView.TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Entropy generation for MHD pulsating stratified liquid flow between two permeable beds
Nonlinear AnalysisIn natural systems such as lakes, reservoirs, and the upper ocean layers, temperature-induced stratified fluid flows are frequently observed. Numerous studies have explored key aspects of these flows, including stability, mixing, and thermal transport ...

Numerical study of heat transfer and flow structure over a microscale backstep
Alexandria Engineering Journal, 2021 This study presents a two and three-dimensional numerical simulations of a flow-through a sudden expansion and contraction microchannels. The finite element method was used to discretize the equations governing the physical model.

Energy Science &Engineering, EarlyView.The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Refinement of Nusselt numbers in drying processes
Mathematical Modeling and ComputingIt is proposed to refine the calculation of Nusselt numbers by considering the mass transfer coefficient in the evaporation zone, which is significantly larger than the molecular mass transfer coefficient of vapour. This refinement aims to address the discrepancy between the elevated Nusselt criteria observed during drying and the criteria determined ...

Energy Science &Engineering, EarlyView.We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.
