流動液体泡沫の加熱円筒回りの熱伝達 ; Forced Convection Heat Transfer from a Cylinder to Liquid-Gas Foam

application/pdf ; An experimental study of heat transfer from a heating surface to a liquid-gas foam flow was conducted under forced convection conditions. A cylindrical heating surface, whose temperature was less than 373K, was employed. Values of heat transfer rate for the foam flow were found to range between those for water and the air, indicating that the foam possesses intermediate cooling ability between water cooling and air cooling. It is also shown that latent heat transfer by the water vapor in the foam is an important factor in heat transfer at high temperature. ; conference paper
