Research on Centrifugal Compressor Vanes Variable Geometry

the study and investigation about centrifugal compressor is being invested in this paper and the [3] objective of this paper is to present Vane consideration and test rig and its flow geometry on the vane surface. Compressor is the devise in which air is compressed with high energy and this energy is used for combuction which is the procedure of the engine after that the fluid is passed in the turbine and it expand through the exhaust and it produce the thrust. The main work of compressor is to produce the high speed with better compression and load .the section of compressor hoses the power for compressor rotor and its main work is to supply the air in sufficient amount to satisfy needs of combustor. When mechanical work of compressor and turbine are converted the potential energy and fuel is added in combustion and after that it expand through exhaust and produce the suitable thrust. The principle behind the compressor is the acceleration of working fluid and it follow the diffusion and to convert the kinetic energy for pressure rice. The primary and initial work is the pressure of the mass of air entering in the air entering and the discharge to the diffuser and the combustion chamber with correct velocity and pressure and temperature. In early days compressor had less efficient than now we have today, we entered the suitable amount of air flow in the compressor and high temperature to improve the laminar flow over the lot of aerofoil at high velocity and pressure. Compressor efficiency is based on least temperature rise, and presently the efficiency of the compressor is 85 to 90%. And the secondary purpose of the engine is to supply the Bleed air to cool hot section parts. Another use of the compressor is to supply the extract air supply for aircraft use. There are only two types of compressor which is centrifugal compressor and axial flow compressor before few years we used centrifugal compressor but now axial flow compressor is running in aviation industry.
