چکیده مقاله
Abstract In this work the numerical results of natural convection and surface thermal radiation in an open cavity receiver with a side wavy wall considering large temperature differences and variable fluid properties are presented. The overall continuity, momentum, and energy equations are solved numerically by using the finite-volume method and the SIMPLEC algorithm. Numerical calculations were conducted for Rayleigh number (Ra) values in the range of 104-106. The temperature difference between the hot wall and the bulk fluid (
