Development of a Numerical Code for TPS Design and High-Temperature and High-Strength material Numerical code for TPS design and development of advanced material using SAGT

摘要

Integrated numerical code for TPS design and high-temperature and high-strength material is developed. Shock Aligned Grid System (SAGT), a method that aligns shock waves with grid system automatically, is adapted to reduce numerical error around a strong shock wave. With Shock the code effectively reduces numerical error due to grid distribution leading to more accurate solution of hypersonic flow. Though various numerical tests, it is shown that the code accurately estimates the recession at the stagnation point of a blunt body.
