Abstract
Oblique wavy surface can achieve very high heat transfer enhancement with small pressure loss penalty because it can produce effective secondary flow without separation. In the present study, applicability of oblique wavy surface to gas-liquid separation in mist flows is investigated. Plate, oblique wavy and sine wavy surfaces are tested by air-water experiment. It is confirmed that oblique wavy surface can completely separate liquid droplets whose sizes are larger than approximately 10 microns.
