Heat Transfer Laboratory
The heat transfer laboratory undertakes basic and applied research on variety problems in convective heat transfer, two-phase flow, and compressible flow. The specific research interests are placed on the following areas:
- Single-phase enhanced heat transfer such as liquid jet impingement cooling.
- Two-phase flow: Topics such as enhanced heat transfer by spray cooling mechanism, liquid-solid particulate transport, and boiling heat transfer.
- Mist cooling of a heated surface is investigated in terms of the liquid droplet deposition characteristics from a turbulent two-phase flow.
- Optical measurement of the particle trajectory and its size using a Laser Doppler Velocimetry.
- Testing and computational analysis of a micro-scale heat flux gage.
- Modeling and computational analysis of a high altitude diffuser which simulates the SSME( Space Shuttle Main Engine) performance.
