| Abstract: | The influences of solid particles in liquid on boiling heat transfer are investigated. It is found that the fluidized particles enhance boiling heat transfer in the lower and middle heat fluxranges and improve the boiling hystesis in boliing incipience .It is proposed that the upward moving particles from the heated surface during the boiling have analogy to the vapor bubbles departed from the heated surface ,a nesw pseudo-boiling mechanism for the fluidized particles in nucleate pool boiling is developed. |
