Abstract: In Turbo jet engines, Gas turbines, High pressure boilers and IC engine applications the heat distribution after combustion is a combined phenomenon of convection and radiation heat transfer. Interpreting the role of each mode of heat transfer in the perspective of increasing the efficiency and reducing the heat loss is one of the prime necessities for thermal power plant, aerospace and automobile industries. Here we analyzed the characteristics of the radiation field by temperature profiles through their variation at different planes of the domain, using an experimental approach. The testing domain, which replicates the size of the IC engine cylinder, is heated to a high temperature using a coil heater and is insulated to avoid external influence. Using ‘K’ type thermocouples arranged in series, the temperatures at various points and at various sections are determined. Correspondingly the Temperature profiles for different section planes are plotted. The propagation of radiation from the source as a function of distance and the effect of wall has been analyzed using the temperature profiles.
