General Temperature Computational Method of Linear Heat Conduction Multilayer Cylinder Original Research Article

According to the axisymmetric heat conduction of monolayer cylinder, a general method was deduced to calculate the axisymmetric temperature of linear heat conduction multilayer cylinder. Four types of boundary conditions were summarized and formulas for each type were derived. Then, a general calculating program was developed. Four temperature formulas could be expressed by a uniform equation, and the intermediate interface temperatures of axisymmetrical linear conduction multilayer cylinder satisfied tridiagonal linear and nonlinear systems of equations, which could be solved with the pursuit method and the Newtonʹs method, respectively. With the calculating program, the temperature at any point of linear heat conduction multilayer cylinder could be obtained.
