High reputation 713&718 Nimonic Waspaloy Investment Casting Gas Turbine

Diffuser can be divided into vaned diffuser and vaneless diffuser. Its working principle is to convert velocity energy into pressure energy by making use of the different cross-sectional areas of flow passage. Vane diffuser restricts the flow direction of air flow through the shape of blade, thus shortening the overall structure size of diffuser channel. In axial compressors, vaneless diffusers are usually used after the last stage to recover the velocity energy of air flow. Of course, a similar diffuser will be used at the outlet of the turbine expander.
