Heat Transfer to Boiling Liquids

HEAT TRANSFER TO BOILING LIQUIDS

Heat transfer to boiling liquids occurs in a number of operations such as distillation and evaporation. Heat is transferred by both conduction and convection in a process further complicated by the change of phase that occurs at the heating boundary. When boiling is induced by a heater in contact with a pool of liquid, the process is known as pool boiling. Liquid movement is derived only from heating effects. In other systems, the boiling liquid may be driven through or over heaters, a process referred to as boiling with forced circulation.
