Transient Analysis of Coupled Natural Convection and Surface Thermal Radiation in a Tilted Open Cavity
Keywords:Open cavity, transient natural convection, thermal radiation
Numeric results of the transient heat transfer by natural convection and surface thermal radiation in a tilted open cavity are presented. The conservation equations in primitive variables are solved using the finite volume method and the SIMPLEC algorithm. The transient results are obtained for a Rayleigh number of 106 and five inclination angles (0Â°, 45Â°, 90Â°, 120Â° and 180Â°. The numerical model predicts flow instabilities for inclination angle of 0Â°, which avoids reaching the steady state. The steady state is reached after a long time for f=180Â°.
