Diffuser is one key component of the gas turbine combustor following the compressor. Its primary function is to slow down the air flow delivered by the compressor in order to promote efficient combustion and avoid large total pressure losses. The impacts of pre-diffuser wall angle and dump gap ratio on the performance of dump diffusers have been discussed in the previous work, but few work has been undertaken on designing diffusers with greater pre-diffuser wall angle. It was observed that apparent flow separation occurred on pre-diffuser wall when pre-diffuser wall angle amplified to certain degree. The pre-diffuser exit flow was distorted, indicating that the uniform exit conditions typically assumed in the diffuser design were violated. Skew distribution of the pre-diffuser outlet flow can result in strong transverse mixing for liquid, the total pressure loss of pre-diffuser increases significantly.
Material of turbine is Supperalloy and widely used in Marine Engine, Gas Turbine, Industrial Engine, Turbojet, Steam turbine, Aero turbine etc.
Process of turbine are investment casting, different country have different translate, Lost Wax Casting, Vacuum Casting, Precision Casting, Silica Sol Casting etc.
