The display of multi-dimensional flows in turbomachinery

Abstract

Introduction: As part of a general development of computational techniques for multidimensional flows through turbomachine passages and over turbomachine blading at the M.I.T. Gas Turbine Laboratory, display techniques and programs have been developed for the visualization and interpretation of the computed flows. These display programs have been developed for the Adage AGT-30 system implemented at the Electronic Systems Laboratory at M.I.T. In the present report two major programs are described and illustrated. These are programs for the display of the turbomachine blading and flow passage geometry and for the display of contours of any scalar fluid variable in the flow passage. The manner in which the system is used is as follows. The turbomachine blading and flow passage geometrical data exist on an Adage tape. The output of the fluid dynamic calculation which is presently done on the OS/370 system is connected on OS/370 to an Adage compatible tape. This tape which represents the computed flow is then viewed on the Adage system.
