![]() The static pressure rise in the impeller may roughly equal the rise in the diffuser. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The first is for a new large passenger aircraft, and the second for a new fighter aircraft. The following equation shows this specific energy input. This second edition of Cumpstys self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engines features two engine design projects. They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. Figure-0.4 Control volume for a generalized turbomachineĬentrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.
