Supercomputer simulation of physicochemical processes in solid fuel ramjet design components for hypersonic flying vehicle

Abstract

A step-by-step computer simulation variant for making scramjet mathematical model is offered. The report considers an approach related to 3D mathematical models development of scramjet components further reduced to 1D models. Mathematical models of physicochemical processes in combustor cooling system are discussed with the aim of subsequent engine performance optimization depending on fuels used. Then 1D separate component models are used to make up a full-scale scramjet model. The one-dimensional models allow calculation times significantly reduce, and the simulation accuracy is conditioned by precision of 3D models to 1D models reduction.
