Comparison of sub-models of Heat transfer in network model of fire

Three sub-models of heat transfer across wall in network model of fire are analyzed. The software predictions with the three methods are compared with data of Japan one another by illustration. It shows that for three-node simple building, Both of half-infinite heat transfer sub-model and finite heat transfer sub-model agree well with the data of Japan, half-infinite heat transfer sub-model has a temperature deviation of less than 5% with finite heat transfer sub-model, While the method of heat insulation more than 40%.
