Improved Hypersonic Jet Interaction Modeling with Propulsion Exhaust Chemistry

BlazeTech is collaborating with University of Colorado using their hypersonic CFD code LeMANS as a platform on which to integrate a novel combustion code that iteratively adapts its chemical model based on the local flow structure. In this way, the chemistry and fluid mechanics are closely coupled, and simplified models may be leveraged for their low computational cost when more detailed models are unnecessary. Thus, liquid and solid propellant chemistries can be treated. This development offers the potential of accurate predictions of jet flow interactions and afterburning at reasonable computational cost.
