RVCQ3D v. 406


RVCQ3D (Rotor Viscous Code Quasi-3-D) is a computer code for analyzing inviscid and viscous blade-to-blade flows in turbomachinery. It includes the quasi-3-D effects of rotation, radius change, and variable stream surface thickness. Simple flat plate and duct geometries can also be analyzed.


Formulation and differencing schemes

RVCQ3D solves the Euler or Navier-Stokes equations written on a surface of revolution. The equations are written in an (m,theta)coordinate system, where m is the arc length along the surface and theta is the circumferential direction. The stream surface radius and thickness are assumed to be known functions of m, and are usually obtained from an axisymmetric throughflow analysis.

Turbulence models

All turbulence models include transition and roughness effects.

Computer requirements

All codes are supplied as Fortran source code and require a Fortran 90 compiler for use. The Cray, Compaq, GNU, Intel, and SGI compilers have all been used successfully. The codes are usually run on Linux systems, butwill run on on a PC or Mac. Parallel processing is available on multi-core computers using OpenMP directives. Check the Fortran Store for information on Fortran compilers

Graphical output

No graphical output is provided with these codes, but access to some CFD visualization software is required to view and evaluate the grids and solutions. Grid and solution files are in standard PLOT3D format and can be read directly and plotted with the public-domain CFD visualization tool PLOT3D, or the commercial tools FieldView, TecPlot, or EnSight CFD. Check the following web sites for information on CFD visualization software.
