In CFD analysis of radiant cooling panels, it is challenging to accurately reproduce the detailed geometry, which often leads to the use of simplified models. Consequently, the material volume in the constructed model is altered, resulting in a heat capacity that differs from that of the actual radiant panel. This discrepancy makes it difficult to accurately predict dynamic heat dissipation, thermal storage, and surface temperature variations in non-stationary analyses. To address this issue, a heat capacity correction method is proposed to enable the CFD model to accurately replicate the surface temperature response of the radiant panel under non-stationary conditions.
