Prospects of the multi-scale approach to the computer aerophisics problems
Prospects and problems of multi-scale approach for solution of problems of computational aerophysics are presented.
Definitions of the physical mechanics, the multi-scale approach, and the integral models of the physical mechanics
are presented. Examples of multi-scale approach and integral models for problems of aerothermodynamics of space
vehicles are discussed.
As an example, these models are illustrated for aerothermodynamic prediction of space vehicle MSRO (Mars Sample
Return Orbiter) with using computer code NERAT (Non-Equilibrium Radiation Aero Thermodynamics). Test case
TC3 suggested by the European Space Agency is discussed.
Обсуждаются перспективы и проблемы многоуровневого подхода к решению задач компьютерной аэрофизики. Дано определение физической механики, многоуровневого подхода и интегрированных моделей аэрофизики. Приводятся примеры реализации многоуровневого подхода и интегрированных моделей к решению
задач компьютерной аэрофизики спускаемых космических аппаратов.
В качестве примера реализации интегрированных моделей физической механики представлены результаты
расчетов аэротермодинамики космического аппарата MSRO (Mars Sample Return Orbiter) с использованием
компьютерной программы NERAT (Non-Equilibrium Radiation Aero Thermodynamics). В качестве тестовых
точек, допускающих последующее сравнение с расчетными данными других авторов, использованы размеры
КА и траекторные параметры, установленные рабочей группой Европейского космического агентства по
излучению высокотемпературных газов (тестовая задача TC3).
