    2014.05.22   the Heat Transfer Society of Japan   EEnhancement of the critical heat flux in saturated pool boiling using honeycomb porous media

    Winner: Shoji MORI, Kunito OKUYAMA

     View Summary

    The enhancement of the critical heat flux by the attachment of porous plates on the heated surface has been investigated experimentally under the saturated pool boiling conditions. In the case that a honeycomb porous plate is applied, the CHF has increased up to 2.51 MW/m2, which is approximately 2.5 times that of a plain surface (1.01 MW/m2). It has been found that the keys for the enhancement of the CHF are the automatic liquid supply due to capillary action and the reduction of the vapor counterflow resistance due to separation of liquid and vapor flow by the honeycomb porous structure. A simplified one-dimensional capillary - limit model, in which the pressure drop due to liquid and vapor flow is balanced by capillary force, has been applied to predict the CHF. The calculated results have been compared with the observed ones.
