Analysis on Three-Dimensional Inverse Load Problem of Radiation Heat Transfer.

Abstract

A method is developed to solve 3-dimensional inverse load problem on radiation heat trasfer. In the present study, the heat flux and temperature distributions of many heater elements arranged along inside a rectangular furnace walls are shown to be estimated from the boundary conditions assigned to the heated objects in the furnace by using the newly developed solution method using singular value decomposition (SVD) technique. The statistical error contained in READ values that represent the radiative heat exchange between elements in the system and are calculated by using the Monte Carlo method are corrected by using smoothing technique. This reduces the scatter of the results contained in the inverse calculation and also reduces the computation time remarkably.
