Abstract
Convective heat transfer from an open cavity has been studied in the range of Reynolds numbers from 104 to 105 in the case of depth-to-width ratio H/L=1.0. Convective heat transfer from an open cavity is treated by the following two phenomena one the heat transfer related to the temperarure difference between the wall and the fluid in the open cavity, the other the heat transfer related to the temperarure difference between the fluid in the open cavity and the external main stream. In part 1, effect of temperature non-uniformity on the wall surface for convective heat transfer is experimentally studied by the cavity model which is made of brass . In the presnt report, effect of temperature non-uniformity on the wall surface for convective heat transfer is studied by numerical calculation of heat transfer model. Heat transfer rate obtained by numerical calculation almost coincide with the existing experimental data obtained under the conditions that there is temperature non-uniformity on the wall surface of the open cavity.
