Five Computer Codes for Analysis of Turbomachinery

A suite of five computational fluid dynamics (CFD) codes has been developed for analysis of flows in turbomachinery. Two of the codes are used to generate two-dimensional (2-D) or three-dimensional (3-D) grids that describe the turbomachinery blade geometry. The other three codes solve the Navier-Stokes equations on those grids to predict the performance of the blades. Three mathematical models of turbulence that include effects of flow transition and roughness are available. The codes are applicable to fans, compressors, and turbines in both axial and radial machines.
