Mach 14 Flow Restrictor Thermal Stress Analysis

Abstract

The objective of this study was to determine the effects of heating and mechanical pressure loading on the flow restrictor plate used in the Mach 14 leg of NSWC/WO hypervelocity Wind Tunnel. Included in this report are the procedures for model generation using PATRAN-G, model translation into ABAQUS format, transient heat transfer analysis, thermal stress analysis, results translation from ABAQUS to PATRAN-G, and the method used to determine the heat transfer film coefficients needed for ABAQUS. The results of these analyses are reviewed and recommendations are made for future analyses. Keywords include: Flow restrictor; Thermal stress analysis; ABAQUS Analysis program; PATRAN-G graphics modeling program.
