Q1. A metal alloy structure (k = 17 W/m K) has a length of 5.3 cm, a perimeter of 11 cm, and a cross-sectional area of 5.13 cm². The structure is exposed to hot gas from the combustion chamber at 973°C with a convection heat transfer coefficient of 538 W/m²K. The base of the structure maintains a constant temperature of 450°C. Determine the heat transfer rate to the metal structure and temperature at the tip by performing two COMSOL simulations: Simulation 1: rectangular shape, 1.19x4.31 cm Simulation 2: circular shape with diameter given by the hydraulic diameter (i.e. D = 4A/p)
