DOI: 10.1016/j.nucengdes.2019.110460
Abstract: Abstract The backward facing step geometry (BFS) is a representative geometry for sudden expansions in pipe, duct and channel flows. While this type of geometry by itself is not a part of engineering components, the… read more here.

DOI: 10.1063/1.4993466
Abstract: Secondary instability of thermocapillary convection was investigated for a half-zone liquid bridge with low Prandtl number fluids. The liquid bridge was suspended between two cylindrical flat disks, which were maintained at different temperatures. The thermocapillary-driven… read more here.
