About Us
The Micro-Scale Heat Transfer Laboratory at UTA is fully equipped for conducting systematic experimental investigations of liquid-vapor phase-change phenomena at atmospheric and pressurized conditions. The lab is situated in a 2,000 sq. ft. floor space devoted solely for the purpose of boiling heat transfer and two-phase flow research.
Two flow boiling test facilities are located in the lab. The first is a low-flowrate boiling loop which can currently accommodate from 50 ml/min up to 1.7 liters/min. The second flow boiling loop can accommodate from 1.5 to 70 liters/min. Both low- and high-flowrate loops are constructed almost entirely with stainless steel and operable up to 10 atm.
High-speed video imaging equipment with digital recording hardware is available for the capture of various boiling phenomena during testing. The current system is capable of frame speeds of up to 600 fps and shutter speeds of up to 1/10,000 of a second. Laser Doppler anemometry is also available to measure the bubble velocity and frequency. Investigations in both fundamental and applied research areas are focused primarily on enhancement of heat transfer.
