Abstract:There Thermography of the skin is an easy method for estimating the vitality and survival area of the skin flaps.

The paper presents the results of simulation of the heat transport in the human tissue by means of 1D numerical model and experimentally obtained data. The model is based on the control volume numerical method with the skin temperature and heat losses to the surrounding as the boundary conditions. The thermodynamical properties of the tissue were taken from the relevant literature. The results obtained by simulation are compared with the data given in lit.[1]. The temperature droop in upper arm tissue of the observed subject is presented graphically, while the temperature distribution on the upper arm surface is given by thermograms.

The goal of the research was to find the relation for determining the heat transfer coefficient between a free streaming water film and metal corrugated surface. The relation between relevant parameters which determine the heat transfer coefficient has been obtained by means of Wilson-plot method using data from the measurement.
