Abstract

A stainless steel tube electrically heated was used to study the incipience of flow boiling in subcooled well wetting fluids (R-12 and R-114) in a wide range of pressure, mass flux and heat flux. A higher temperature excess in the wall must be reached before boiling sets in, than the temperature achieved when boiling has developed. Hysteresis in boiling observed by increasing and decreasing heat flux seems to be ascribed to the small contact angle of refrigerants on surfaces as stainless steel allowing the larger cavities in the wall to be flooded.
