Numerical Investigation of a Transonic Centrifugal Compressor
Journal of Turbomachinery, 2006A three-dimensional Navier-Stokes solver is used to investigate the flow field of a high-pressure ratio centrifugal compressor for turbocharger applications. Such a compressor consists of a double-splitter impeller followed by a vaned diffuser. The inlet flow to the open shrouded impeller is transonic, thus giving rise to interactions between shock ...

The J83 Seven-Stage Transonic Compressor
Journal of Engineering for Power, 1961The J83 turbojet engine was a high-performance, lightweight engine with a maximum thrust of 2450 lb, a diameter of 18 in., and a weight of approximately 300 lb. The compressor for this engine was a seven-stage, transonic, axial-flow compressor with an inlet tip diameter of 15.2 in. and a hub-lip ratio of 0.433.

Understanding Unsteady Flow Features in Transonic Compressors
Computing in Science & Engineering, 2007Applying computational science and engineering to the design and analysis of high-performance compressors makes it possible to understand unsteady flow effects in gas turbine engines. Simulations have produced numerical data of greatly improved geometric, physical, and numerical fidelity than previously possible, helping next-generation engines achieve

Approach to High Performance Transonic Centrifugal Compressor
38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002A single stage transonic centrifugal compressor for a small turbofan engine has been developed. Rig testing has demonstrated 83.2 percents of adiabatic efficiency for 7.5:1 of total to static pressure ratio, using a corrected tip speed of 596 m/sec. This paper mainly presents an impeller blade redesign approach from original blade geometry, based on ...

Experimental Investigation of a Transonic Aspirated Compressor
Journal of Turbomachinery, 2003Abstract The experimental investigation of a transonic aspirated stage demonstrating the application of boundary layer aspiration to increase stage work is presented. The stage was designed to produce a pressure ratio of 1.6 at a tip speed of 750ft∕s resulting in a stage work coefficient of 0.88.
