Two-mode boiling on a horizontal heating wire: effects of liquid subcoolings

Abstract

The steady-state boiling curves of methanol boiled on an electrically heated tungsten wire, including the nucleate boiling curve, the film boiling curve, and the equilibrium line located in between are reported with liquid subcooling as a parameter. As liquid subcooling increases, the critical heat flux becomes greater, the film boiling mode more efficient, and the equilibrium line shifts upwards. A lower liquid temperature results in a more stable nucleate boiling mode. However, at a very high liquid subcooling, the steady-state boiling curves are not influenced by the liquid subcooling.
