Abstract

The main objective of this project is to perform simulations on the effect of energy promoters in an aggressive intermediate gas turbine duct (diffuser). Many approaches and ideas have been used to improve diffuser's size, but flow separation will occur and significantly reduces the diffuser's performance. Therefore energy promoter is introduced to reduce the boundary layer. This can be done by increasing the fluid's momentum and redirect them to oppose the boundary layer, thus reducing its size and adverse effect onto the diffuser. A typical S-shaped diffuser is designed and simulated to become the benchmark for this simulation testing. Then, the diffuser is shortened to create an aggressive diffuser design. Then the energy promoter is introduced, and simulated with various configurations to obtain the best height, and position. The objective is to obtain the best exit static pressure, which ultimately affect the diffuser's efficiency. The result shows the energy promoters works as intended, but still far from reaching the benchmark efficiency of a normal/ideal diffuser. Further testing will be required in three dimensional as well as experimental to realize this technology into the real world.
