Turbocharger Compressor Wheel Design. Earliest compressor wheel design and still used by some manufacturers. Compressor wheels design is one of the greatest factors determining a turbochargers performance. The Lower the blade count on the compressor wheel will help the turbo flow more air than the same compressor wheel with more blades. BorgWarner engineers perform finite element analysis FEA and computational fluid dynamics CFD to optimize wheel durability and performance based on the application needs.
A turbocharger is basically a combination of a compressor and a turbine both mounted on a common shaft. Turbochargers are spinning faster than ever before and subjected to higher temperatures. Used for hot turbine and cold compressor portions of current turbocharger systems Honeywell and ORNL have identified turbocharger housings and turbine-wheelshaft assemblies as priority components for consideration with increased exhaust temperatures Cast. Most compressor wheels have been made from various aluminum alloys. The flatback design is one of the earliest styles of compressor wheels and is best for low boost turbochargers. A compressor wheel with more blades will flow very well at higher boost levels30 psi but will not flow as well at lower boost levels.
Mainly two type of compressors are used in a turbocharger.
In ANSYS _CFX the design of the turbine wheel is done. However there are more and more applications that push the limits of what the current aluminum alloys will stand. Compressor wheels design is one of the greatest factors determining a turbochargers performance. Mainly two type of compressors are used in a turbocharger. Design and Function of a Turbocharger. The exhaust-gas-driven turbine supplies the drive energy for the compressor.
