TWIG-A Computer Program for Calculating Unidirectional Transient and Steady-State Temperature Distributions in One, Two, and Three-Layer Slabs and Cylinders-Constant Heat Flux Applied to Outside Surface,

Abstract

Computer program TWIG was developed to permit calculations of unidirectional heat flow by conduction through solids in one-, two-, and three-layer slabs and hollow cylinders. TWIG also permits comparative study calculations to determine how well a slab can approximate a cylinder. The boundary conditions for the program simulate a suddenly activated plane heat source immediate to the outside surface of the body. The complete program is published in this report together with instructions for its use. Included as appendixes are equations for finding temperature as a function of distance and time for all the geometric configurations considered, a complete listing of the program, input and output data, and solutions to exercise problems.
