| Abstract: | Transfer matrix solution of BEM for transient heat conduction problem isproposed in this paper. By using transfer procedure, the transient temperaturefield of quite irregular and multilayer structure can be analyzed efficiently.This method has some advantages also, such as less input data, high accuracyand less computer memory. This method is suitable for minicomputer tosolve temperature problems of large and complex structure. |
