Review—Computational Methods for Internal Flows With Emphasis on Turbomachinery

Abstract

A review is given of current computational methods for analyzing flows in turbomachinery and other related internal propulsion components. The methods are divided primarily into two classes, inviscid and viscous. The inviscid methods deal specifically with turbomachinery applications. Viscous methods, on the other hand, due to the state-of-the-art, deal with generalized duct flows as well as flows in turbomachinery passages. Inviscid methods are categorized into the potential, stream function, and Euler approaches. Viscous methods are treated in terms of parabolic, partially parabolic, and elliptic procedures.

“…In the past 15 years, considerable improvement has been obtained in the calculation of flows in turbomachinery. Most of these recent computational developments have been reviewed in detail by Moore and Moore [ 1] and McNally and Sockol [2] . This progress is especially exemplified by the important development time marching techniques combined with finite volume, finite difference or finite element approaches for the computation of rotational and/or transonic flows in cascades or stages.…”

Penalty Function Finite Element Analysis of Steady Viscous Incompressible Flow in Rotating Coordinates

“…An extensive literature exists for finite difference calculations of viscous flows in turbomachinery. McNally and Sockol [25] give an excellent detailed discussion of this field up to 1981. Due to length considerations, the literature for finite difference methods is not reviewed in this paper.…”

“…The analysis of three-dimensional, transonic flows in turbomachinery has attracted considerable attention during the recent years (1,2). Three-dimensional solution of such flow problems are generally considered of two types: quasi-three-dimensional solutions and fullthree-dimensional solutions.…”
