AXIAL FLOW TURBINE INTRODUCTION An axial turbine is a turbine in which the flow of the working fluid is parallel to the shaft, as opposed to radial turbines, where the fluid runs around a shaft, as in a watermill.An axial turbine has similar construction as an axial compressor, but it operates in the reverse, converting flow of the fluid into rotating mechanical energy. Reaction ratio is 50 % for 166 2.0-2 Blade and Cascade Nomenclature Since airfoils are employed in accelerating and diffusing the air in a compressor, much of the theory and research concerning the flow in axial compressors are based on studies of isolated airfoils. As the name suggests, these compressors have an axial flow; the air or gas passes along the compressor shaft through rows of rotating and stationary blades. Unlike displacement compressors, dynamic compressors work under constant pressure and are affected by changes in external conditions such as inlet temperature. They use one or more impellers which attach to and rotate with the Informational ppt about air compressors, its types, design, working etc. • Axial turbine have same frontal area as that of the compressor. The blade profile and variation of pressure and velocity in the stage are shown in the Fig. The axial component of velocity is constant throughout the compressor and is equal to 150 m/s. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. Air compressors provide pressurized air to operate tool or instrument air systems. Chmielniak T, Lepszy S, Rulik S (2011) Algorithm for design calculation of axial flow gas turbine compressor – comparison with GTD-350 compressor design. The term describes violent air flow oscillating in axial direction of a compressor ,which indicates the axial component of fluid velocity varies periodically and may even become negative. ; But centrifugal compressors can handle much less gas flow compared to the axial compressors.
