| Abstract: | From the view of the physical model of discrete heat transfer,two points are proved inthe article:First,lumped mass heat capacity matrix model can meet the law of conservation ofquantity of heat;Second,many unreasonable results in time integration of heat transfer canbe avoided by using the model.And also,examples are given to indicate that the model has asatisfying accuracy. |
