What We Do
The Multiphase Flow Laboratory is dedicated to basic and applied research aimed at improving our understanding of multiphase flows. Work has concentrated on single-component liquid-vapor flows for energy conversion systems.
Research
- Liquid-vapor jet pumps for novel refrigeration systems
- Liquid-vapor jet pumps for geothermal power systems
- Liquid-vapor flow in short-tube restrictors for refrigeration systems
- Liquid-vapor flow in flashing-flow nozzles
- Mixing processes in liquid-vapor flows
- Droplet breakup and coagulation in liquid-liquid flows
- Flow regime modeling for steam power-plant flows
- Oil-air flows in screw compressor discharge lines
- Bubble-lift pumps for solar power cycles
- Liquid-vapor flow in short-tube steam traps
- Subcooling sensors for refrigeration systems
Facilities
The Laboratory has experimental facilities in a 400-sq-ft lab in Randolph Hall and a 900-sq-ft lab at the Virginia Tech Airport. Offices are in Randolph Hall. The Randolph Hall lab features a two-level working area to facilitate pumping of saturated liquids, while the Airport lab is used for projects involving high noise levels and/or hazardous materials.
