A FORTRAN PROGRAM FOR DETERMINING THE THERMAL DIFFUSIVITY OF FINITE LENGTH SAMPLES

Technical Report ·
OSTI ID:4726484
A FORTRAN program was written which will make it possible to analyze thermal diffusivity data on the IBM 704. The first description of the physics and mathematics of the method was made by Kennedy. The linear heat flow equation was solved by the method of finite differences. Temspaced points along a finite cylindrical rod. The curves obtained at the two outer points were used as boundary conditions for the finite difference calculus, and the diffusivity was determined by finding the computed solution which gave the best fit to the experimental data obtained at the midpoirt. The program has improvements which prevent the computer from calculating false values for the diffusivity, can operate with any of six preselected mesh sizes, and takes advantage of the capacity of the IBM 704.
