Thermal analysis is an essential and integral part in the design of rocket engines. In the high-pressure engines hot-gas temperatures are very high (they can reach 7000R at the throat area). It is therefore essential to be able to estimate the wall temperature and ensure that the material can withstand such high temperature. Furthermore, an accurate thermal model enables an engine designer to modify the cooling channel configuration for the optimum cooling at high temperature areas. This course presents an overview of various methods for thermal modeling of cooling liquid engines. The cooling methods include: regenerative, film, transpiration, radiative and dump cooling. Simple as well comprehensive computer models are discussed. The participant at the end of this webinar will be able to develop their own rocket thermal analysis model using available public domain software or use existing comprehensive computer programs.
