Turbomachinery Design

Progress achieved in numerical analysis during the past decade now permits the turbo-machinery designer to carry out a wide variety of inviscid, steady flow, two-dimensional calculations for compressible sybsonic and transonic flow fields, including some strongly diffusing flows. Three-dimensional (including viscosity) calculations are under development and should find wide spread use as analysis tools during the next decade. This review offers an introduction to recent advances in numerical turbomachinery design methods guided by the author’s design usage of several of the techniques reported.

This paper discusses aerodynamic design methods of volute casings used in turbocharger turbines. A quasi-three-dimensional (Q-3D) design method is proposed in which a group of extended two-dimensional potential flow equations and the streamline equation are numerically solved to obtain the geometry of spiral volutes. A tongue loss model, based on the turbulence wake theory, is also presented, and good agreement with experimental data is shown.

Flow Field Design

This article reviews the author’s work on inverse methods of flow-field design with prescribed velocity distributions on the boundaries. Such design methods are of some importance, because these velocity distributions, on the boundaries of fluid-handling equipment, determine the boundary-layer behavior and thereby affect the equipment efficiency. The work is limited to design methods for stationary channels with incompressible or subsonic compressible flow. Both two- and three-dimensional design methods are reviewed. The two-dimensional work was done in the early 1950’s and the three-dimensional work in the 1980’s.

Feature Unit

This paper adopts the parameterized designing method of feature assembled and feature unit. For the feature of non-conventional parts, such as welding box and bearer, using the Visual C++ and AutoCAD as soft tools, the system successfully carries out the basic function of feature assembling, the processing of two-dimensional figure, the building of three-dimensional feature, the automatic producing of technical papers, and so on. The integration idea and design methods of this system can be served as the preference to CAD/CAPP integration for other non-conventional parts.
