A New Anisotropic Four-Parameter Turbulence Model for Low Prandtl Number Fluids
Fluids, 2021 Due to their interesting thermal properties, liquid metals are widely studied for heat transfer applications where large heat fluxes occur. In the framework of the Reynolds-Averaged Navier–Stokes (RANS) approach, the Simple Gradient Diffusion Hypothesis (

Horizontal Shear Instabilities at Low Prandtl Number [PDF]
The Astrophysical Journal, 2020 Abstract Turbulent mixing in the radiative regions of stars is usually either ignored or crudely accounted for in most stellar evolution models. However, there is growing evidence that such mixing is present and can affect various aspects of a star’s life.

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

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 ...
