A REGULAR REGIME METHOD FOR USE IN THE DETERMINATION OF THERMAL PROPERTIES OF POROUS SOLIDS.

Author(s) : RORIZ L. F.

Summary

A STEADY STATE METHOD, SIMULTANEOUSLY DETERMINING THE THERMAL PROPERTIES OF SOLIDS IS PRESENTED FOR THE CASES OF THE PARALLELEPIPED AND OF THE FINITE CYLINDER. THE METHOD IS BASED ON THE THREE-DIMENSIONAL SOLUTION OF THE HEATING OR COOLING OF SOLIDS. IT CAN BE APPLIED TO POROUS OR NON POROUS MATERIALS. THE RESTRICTIONS DUE TO BOUNDARY CONDITIONS (VARIATIONS OF THE FLUID SURROUNDING THE SAMPLE) ARE SMALL: TEMPERATURE SHOULD CHANGE RAPIDLY SO THAT THE TIME REQUIRED BY THE FLUID TO REACH ITS FINAL TEMPERATURE IS LOW IN COMPARISON WITH THE TIME REQUIRED BY THE POINTS OF THE SOLID, THE TEMPERATURE OF WHICH IS MEASURED, TO REACH THE SAME TEMPERATURE ; THE CONVECTION COEFFICIENT SHOULD BE CONSTANT DURING THE TEST. THERE IS NO RESTRICTION FOR TEMPERATURE AND RELATIVE HUMIDITY.
