摘要：In the presentstudy, a computational investigation is carried out within a model room of which dimensionshas also been given in international standards for experimental approaches. In accordance with the experimentalstandards, the analyses are realized at the room dim ensions of (L x H x W= 4 x 3 x 4 m), and at the thermal boundaryconditions of (T c = 35 50 o C), (T w = 15 24 o C), (T f = 15 24 o C). As a result of iterations conducted using acomputational fluid dynamics package program code, each corresponding to a case study, convective, radiative, andtotal heat fluxes from radiant heated ceiling are obtained, and afterward using relevant reference temperature proposedin the literature, heat transfer coefficients pertaining to convection, radiation, and total heat tran sfer have been found.In conclusion, average heat flux values of 95.83 Wm 2 and 17.49 Wm 2 are gained through the examined radiant heatedceiling, by means of radiation and convection, respectively. This denotes that roughly 85% of total heat transfer fromthe ceiling arises through radiation that is very compatible with the relevant literature. Finally, spanning the entiredifferent case studies, average convective, radiative, and total heat transfer coefficients of 1.1 Wm 2 K 1 , 5.4 Wm 2 K 1 ,7.6 Wm 2 K 1 ar e acquired.
