Thermal heat loss tends to be used to express the net thermal efficiency of insulation effect.
热损失一般用热网热效率来表示其保温效果。
Results showed that the net heat loss on the downstream side of the jet nozzle could reach 20 ~ 30% of total heat flux. Therefore it can not be neglected in calculating the wall temperature.
结果表明,喷管下游端的壁面辐射损失高达壁面总热流的20 ~ 30%,在壁温计算时不容忽略。
