User's manual for CONTA: program for calculating surface heat fluxes from transient temperatures inside solids
This report is a user's manual for program CONTA. This program provides a means for the numerical solution of the nonlinear, one-dimensional planar, inverse heat conduction problem (IHCP). The IHCP is the problem of estimating the surface heat flux history utilizing measured transient interior temperatures. The surface temperature is also estimated. Up to four measured temperature histories can be used; they can be any location in the body and are given at uniformly-spaced discrete times. The basic equations are given in differential form and also in the finite difference form that is used in the program. The numerical inverse heat conduction algorithm is given in detail. The program is described and detailed instructions are given regarding the input. Two test cases are given to illustrate the input and the output. These test cases also provide insight into the engineering use of the program. A discussion is given of the selection of certain critical input quantities. Methods of investigating the accuracy of calculations are also included. The use of CONTA for calculating heat transfer coefficients is discussed.
