Investigation of the Thermal Response of a Gasdynamic Heater with Helical Impellers. Calspan Report No. 6961-A-1

摘要

A gasdynamic heater, capable of producing contamination-free gas streams at temperatures up to 9000 exp 0 K, is being developed by the Vulcan project. The design of a cooling system for the case parts and the associated thermal analysis are a critical part of a successful design. The purpose of the present work was to perform a preliminary cooling passage design and complete thermal analysis for the center body liner, end plate liners and exit nozzle. The approach envisioned for this work was the use of a set of LLNL finite-element codes, called MAZE and TACO2D. These were to be used at LLNL in a series of visits by the Calspan principal investigator. The project was cancelled shortly after the first of these visits; this report contains a summary of the work accomplished during the abbreviated contract period, and a review of the items that will need to be considered when the work is resumed at some future date.
