HEAT TRANSFER FOR FILN BOILING OF A LIQUID ON A VERTICAL HEATED WALL IN A POROUS MEDIUM

The paper presents results of the modelling heat transfer at film boiling a liquid in porous medium on vertical heated wall. Such processes are observed cooling high-temperature surfaces pipes, microstructural radiators etc. Heating conditions wall were constant temperature or flux.
 An analytical solution was obtained for problem fluid flow and using model Darcy-Brinkman. It shown that less intensive than absence (free flow) further decreased with decreasing permeability medium. A sharp decrease Darcy numbers lower five. predictions coefficients qualitatively agreed data [14] though demonstrated values flux.
