Different diameters of cylindrical tungsten rods (acting as positive terminals) were connected to a prototype heat shield (50mm diameter). The Ansys simulation is ‘Steady-State Electric Conduction’ coupled with ‘Transient Thermal’ in duration of 30 seconds with a current rating of 100A shown in Fig.3.2. The target is to replicate temperature distribution at 180\(^0\) angle of attack.
