How surface microstructures affect #Leidenfrost droplets.
Numerical results show that pillar size and spacing control vapour escape under the drop, which can delay or suppress the Leidenfrost state and modify #droplet rebound.

Numerical investigation of a novel regenerative cooling channel for methane-fueled scramjet The extreme heating loads in the scramjet thrust chamber and the limited coolant mass flow rate are obstacles to effective thermal performance. This study propo

How do #hypersonic engines survive extreme temperatures? A numerical study investigates a novel regenerative #cooling channel where methane fuel flows through the engine walls, helping control heat while feeding the combustion system.

On the flow topology and mean flow characteristics of the swirl jet upon impingement Jet impingement enhances heat transfer and is characterized by the complex flow patterns formed when a jet impacts a plate aligned normal to it. While tradition

Smaller jet-to-plate distances intensify turbulence in swirl jets, highlighting how impingement geometry controls flow patterns. Key insights for heat management and surface-fluid interaction studies.
