A mathematical simulation model of the skin for evaluation of surface temperature gradients resulting from local variations in metabolism and blood flow.

A very simplified 2-dimensional simulation model of the skin and subcutaneous tissues is presented. The model is given in an annotated FORTRAN computer program with suggested numerical values for all the required constants. The model can be used to evaluate surface temperature gradients and subcutaneous thermal gradients which result from deviations of subcutaneous blood flow or heat production.
