Air Convection in the Active Layer of Rock Glaciers
Coarse blocks are an abundant surface cover in mountainous permafrost landscapes. In this coarse blocky layer, air convection occurs and has a significant influence on the ground thermal regime of the underlying permafrost.

Compressible Analysis of Bénard Convection of Magneto Rotatory Couple-Stress Fluid
Thermal Instability (Benard’s Convection) in the presence of uniform rotation and uniform magnetic field (separately) is studied. Using the linearized stability theory and normal mode analyses the dispersion relation is obtained in each case. In the case

A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Performance study of a solar chimney air heater
The thermal efficiency of conventional solar air heaters could be significantly improved by making some design configurations. In this study, a solar chimney air heater was employed and the effect of glazing, fins and convection (natural/forced) on the ...
