| Regarding compressor volutes, it is strongly believed that quite a substantial additional pressure recovery and gain in efficiency can be obtained from a good volute design. For an industrial or a turbocharger compressor stage with a well-designed volute, typically, there is an efficiency loss of between 2-5 percent in the volute. Nearly, all arising from the inability of the volute to use the radial kinetic energy out of the diffuser and from secondary flows.; The objective of this work is to develop a design and analysis tool for compressor volutes and turbine scrolls. The work will review volute and scroll technology, study theoretical volute and scroll flow, and develop a design procedure for compressor volutes and turbine scrolls. The major portion of the work is programming visual basic where the major task is to create subroutines to generate the volute profile and cross-section details. The objective of using visual basic is to make the software a windows based application and easy to use. |
