Plume Overview:

• Missile Plumes

• Aircraft /Rotorcraft Plumes
CRAFT Tech personnel are leading experts in the modeling of missile exhaust plumes for signature characterization. The SPF code which is an industry standard was originally developed by the CRAFT Tech founding members. More recently, CRAFT Tech has been actively involved in developing more sophisticated NS/PNS based plume flowfield models which can accurately resolve three-dimensional effects. In addition substantial work is also being done in the development of advanced turbulence models and turbulence-chemistry interaction formulations that can be used to characterize plume mixing and combustion over the wide range of conditions encountered over the boost phase.
