“…For radiant heat transfer, the radiant heat transfer q 0 rad , between the temperature of the outer layer of the multilayer structure and the temperature of the outside environment must be considered, as shown in eqn (17). For convective heat transfer, the convective heat transfer q 0 conv;o , between the outer surface of the multilayer structure and the outside environment is considered as shown in eqn (18), and the convective heat transfer q 0 conv;i , between the inner surface of the multilayer structure and the air in the passenger compartment is considered as shown in eqn (19).…”
