A Study of Minimum Heat Flux (MHF) Point in Pool Boiling of Platimun Small Ball

Abstract

In the heat treatment of alloy materials, it is very important to understand the film boiling minimum heat flux (MHF) point temperature quantitatively. The platinum small ball heated high temperature has been quenched into water and into an aqueous polymer solution in an arc shape. MHF point temperature tends to increase with increasing water subcooling. In quenching in the aqueous polymer solution, the MHF point could be clearly discriminated on the boiling curve. However, in the concentration below 15 vol%, striking change on the MHF point temperature was not recognized.
