Summary

A MODEL HAS BEEN DEVELOPED TO SIMULATE THE THERMAL HISTORY OF A KIDNEY DURING SURFACE COOLING. IT IS IMPLEMENTED FOR BOTH A HOMOGENEOUS TISSUE MASS AND A NONHOMOGENEOUS COMPOSITE ORGAN WITH UNIQUE THERMAL PROPERTIES. THERMAL CONDUCTIVITY AND DIFFUSIVITY WERE MEASURED IN FOUR DIFFERENT TISSUES OF THE KIDNEY. THESE MEASUREMENTS DEMONSTRATED UP TO A TWO-FOLD VARIATION IN THE VALUES OF THE TRANSPORT PROPERTIES IN THE DIFFERENT TISSUES. LOCAL TEMPERATURES OBTAINED USING THE HOMOGENEOUS AND THE NONHOMOGENEOUS MODELS MAY VARY BY 15% OF THE TOTAL TEMPERATURE DIFFERENTIAL WITHIN THE SYSTEM.
