A PRELIMINARY DIGITAL COMPUTER PROGRAM (FORTRAN) FOR THREE-DIMENSIONAL HEAT CONDUCTION

A FORTRAN coded program was developed to calculate temperature distributions due to transient or steady state conduction heat transfer in one, two, or three-dimensional systems. Calculations in the program are based on a finite difference solution of the conduction equation in cylindrical coordinates. The system may be made of a group of different materials and may have distributed sources of heat. Applicability of a given problem to the program depends primarily on the boundary conditions available in the program. The program is written to provide for a choice of surface temperature or surface conductance for the boundary condition on the cylindrical surface when the conductance subroutine is included. (Author)
