Web1 mrt. 2024 · A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. Diffusers are used to slow the fluid's velocity while increasing its static pressure. The fluid's static pressure rise as it passes though a duct is commonly referred to as pressure recovery. In contrast, a nozzle is often intended to … Weblighted. The focus will be on thermodynamic modeling utilizing techniques common in industry, such as: the Brayton cycle, component performance maps, map scaling, and de-sign point criteria generation. In general, these topics will be viewed from the standpoint of an example turbojet engine model; however, demonstrated concepts may be adapted to
