The purpose of this report is to model a High Pressure Sodium (HPS) light bulb. Velocity and heat transfer profiles were computed to determine the optimal configuration of heat evacuation using a liquid coolant. In this simulation, water is forced over the bulb to evacuate the large amount of heat that the HPS system produces. The results obtained show the velocity and heat transfer profiles for varying geometries of the HPS bulb. These conclusions can be used to optimize both the flow of coolant and the position of the inlet and outlet on the outer jacket to maximize operating efficiency.
