Computer Program for Generating Input for Analysis of Impingement-Cooled, Axial-flow Turbine Blade.

Abstract

A computer program called TACTGRID has been developed that generates the geometrical input for the TACT1 program, a program that calculates transient and steady-state temperatures, pressures, and cooling flows in an impingement-cooled turbine blade. Using spline curves, the TACTGRID program constructs the blade internal geometry from the previously designed external blade surface and newly selected wall and channel thicknesses. TACTGRID generates the TACT1 calculational grid, calculates arc lengths between grid points required by TACT1 as input, and prepares the namelist input data set used by TACT1 for the blade geometry. In addition, TACTGRID produces a scaled computer plot of each blade slice, detailing the grid and calculational stations, and thus eliminates the need for any intermediate drafting. (Author)
