Computational Fluid Dynamics (CFD) is the process of numerically solving fluid dynamics equations to predict resultant flow fields. It is used to model a rich variety of flow phenomena, as well as to define thermal and structural loads on bodies immersed in fluids.
ATA is experienced in performing CFD analyses for aerospace and industrial customers. Our services include analysis of subsonic, transonic, supersonic, and hypersonic flow regimes, as well as single phase, multi-phase, and reacting flows. Typical applications include flows over launch vehicles and stands, airframes and airframe components, rocket plumes, fuel tanks, heat exchangers, and turbomachinery.
We are also experienced in solving complex fluid-structure interaction (FSI) analysis problems including development of cutting-edge FSI methods for hypersonic vehicles under funding from the Air Force Research Laboratory. Detailed descriptions of some of our CFD and FSI work are available on our technical publications web page.
CFD Analysis Process
