Flow Physics and Thermofluids Modeling Group

When a water droplet is in free fall, gravity accelerates it downward until it is balanced by the upward push of air resistance, allowing the drop to reach a constant speed called terminal velocity. Contrary to the classic teardrop myth, falling water actually takes on different shapes depending on its size. Small droplets remain perfectly spherical due to surface tension, while larger ones are flattened by air pressure into a "hamburger bun" shape before eventually breaking apart.

Vortex generators are passive methods of heat transfer enhancement in any thermal system. However, more research is needed to compare the effects of vortex generators having unique shapes on the flow distribution for high heat transmission. A Therefore, this CFD study aims to propose a total of five novel vortex generator shapes applying modification on a rectangular VG shape, analyzing and comparing the heat transfer and pressure drop properties in a rectangular channel for the Reynolds number varying in the range of Re=4000–11,000.
