Расчёт нагрева поверхности затупленного конуса в высокоскоростном потоке при помощи коммерческих кодов



Calculation of Sphere-Cone Heat Transfer in High-Speed Flow with Commercial Software

The most common turbulence models and the validation results brief overview is given. Calculation results of the high-speed flow around blunted cone are presented. Heat fluxes on sphere-cone surface are obtained with three commercial soft and compared with exper-imental data. Tasks statements in software systems are as close as possible to each other. The influence of the turbulence presence on the surface heat flux value is shown.

Приведён краткий обзор наиболее распространённых моделей турбулентности и име-ющиеся для них результаты валидации. Произведён расчёт обтекания затупленного по сфере конуса высокоскоростным потоком с помощью различных коммерческих кодов. Постановки задач в программных комплексах максимально приближены друг к другу. Проведено срав-нение значений плотности теплового потока на поверхности конуса, полученных численно, с экспериментальными данными. Показано влияние наличия турбулентности в расчёте на величину поверхностной плотности теплового потока.
