Pore-scale conjugate heat transfer of nanofluids within fibrous medium with a double MRT lattice Boltzmann model

Lei Zhang et al.

Summary: This study investigates the conjugate heat transfer of nanofluids within fibrous medium at pore scales, utilizing correction terms projected into the thermal MRT LB scheme to handle heat flux discontinuities near complex interfaces. A random-walk-based stochastic model is used to generate the fibrous medium. The results show that for conjugate heat transfer without convective flow, steady-state temperature profiles are independent of the fiber-to-fluid thermal conductivity ratio, while for conjugate heat transfer with convective flow, heat transfer is enhanced with larger ratios. Additionally, high Reynolds numbers dominate the heat transfer process with a considerable decrease in temperatures for different ratios. The 3D pore-scale temperature distributions are provided to demonstrate the capability of the current conjugate thermal LB model.

Comparison of LBM and FVM in the estimation of LAD stenosis

Jian Liu et al.

Summary: The study conducted blood flow simulations for 12 patients with left anterior descending stenosis using lattice Boltzmann method (LBM) and finite volume method (FVM), and found that the results were consistent between the two methods. Although there were slight differences in local flow patterns in highly stenotic regions, overall the simulations were in agreement. Comparison with invasive fractional flow reserve (FFR) measurements showed that non-invasive diagnosis generally matched FFR, but could sometimes underestimate or overestimate the degree of stenosis due to discrepancies between physiological and simulation conditions.

Modeling of gas porosity and microstructure formation during dendritic and eutectic solidification of ternary Al-Si-Mg alloys

Mengdan Hu et al.

Summary: A 2-D multi-component and multi-phase cellular automaton model coupled with the Calphad method and finite difference method was proposed to simulate gas pore formation and microstructures in the solidification process of hypoeutectic Al-Si-Mg alloys. The model can reproduce interactions between hydrogen microporosity formation, growth of dendrites and eutectics, and competitive growth among gas pores of different sizes. Investigating the influences of initial hydrogen concentration and cooling rate, it was found that the main portion of porosity formation occurs in the eutectic solidification stage.
