Computational Fluid Dynamic techniques have been long used in the aerospace industry to predict in-flight characteristics of military and commercial aircrafts, missiles or space vehicles. CFD simulations can provide critical design information such as lift, drag, and thermal loads. The CAESIM package includes advanced capabilities for aerodynamic analysis of bodies in turbulent compressible flows.
CAESIM simulates the highly compressible turbulent flow field around a missile in the hypersonic flow flight regime. Critical parameters such as skin heating characteristics and/or shock wave interactions are directly available from the numerical simulations. Total Variation Diminishing (TVD) schemes are implemented to guarantee a sharp capture of shock waves and pressure fonts around the missile.
Hypersonic Flow
The design of hypersonic flight aircraft, rocket propulsion systems, and missile systems require solving complex fluid flow and chemical combustion problems. Chemical reaction plays an important role when the temperature of a fluid is very high.
Analysis of unsteady compressible flow problems invariably involves the resolution of shock waves internal to the flow domain. The development of high-resolution TVD schemes allows for solving problems involving unsteady compressible flow.
