Observe two-phase flow through inverted-U shape tube with temperature and pressure variation.
？
Trace cavitation bubbles (by sudden pressure drop) and boiling bubble (by heating).
？
Identify the mechanism of gas accumulation using ultrasonic transducer, and measure the characteristics of two-phase flows using impedence meter and high-speed camera.
Flow Instability in a narrow rectangular channel
Experimental study on ONB, OSV, and OFI incipient for a narrow rectangular channel heated from one side
？
Constant mass flux approach is consistent with constant heat flux approach
？
Influence of mass flux, heat flux, and inlet subcooled temperature on the ONB and OFI phenomena is observed.
Pool boiling experiments at various surface orientations
Study bubble behaviors and Critical Heat Flux (CHF) on PCB heater at 0, 45, 90, 135, and 180 degree surface orientations
？
Investigate effects of surface orientations on ONB heat flux, and observe bubble behaviors on the heated wall
