Thermochemistry Modelling in an Open Space DSMC Code
Hypersonic vehicles which typically operate in rarefied gas environments and are subject to extremes of velocity and altitude, so it is important that the aerodynamic and thermal loads on the vehicle are properly characterised if the feasibility of the vehicle design is to be accurately assessed. The vehicle may also encounter gasside chemical reactions that can have a significant influence on aerodynamic performance and vehicle surface heat flux . Numerical models which fail to incorporate such reacting flows miss out on an essential part of the flow physics surrounding the vehicle.
