The temperature field gives a general idea about the thermal distribution efficiency along the heat shield. The variation of temperature field (between stagnation points and shoulder ends) with changing diameter of tungsten rod is presented on Table 4.1. It appears that cylindrical tungsten rod of 10mm thickness gives the best temperature field of 91% along the heat shield material.
