WHAT IS CFD? Computational Fluid dynamics (CFD) is the numerical simulation of fluid flows. CFD simulations are frequently used to provide insight and guidance in the design and analysis of fluid systems. Engineers and researchers in the aerospace, automotive, power and chemical industries as well as universities rely on CFD to supplement experiments and analytical methods. A CFD analysis begins by generating a model, or grid, of the domain to be analyzed. The domain is represented by a finite number of points, connected as a mesh. At each of these mesh points, a flow solver will solve conservation equations for mass, momentum, and energy (the Navier-Stokes equations) to obtain a prediction of the fluid pressure, velocity, and other quantities. The challenge lies in the fact that no single computational method is applicable to all classes of problems. CRAFT Tech® is therefore actively involved in the development of innovative methods to treat increasingly complex flowfields. |

CRAFT Tech is an industry leader specializing in the simuation of Aeropropulsive and Combustive/Multiphase Flows for aerospace and commercial applications. We have developed the following codes for performing fluid flow simulation of complex reacting turbulent flowfields: CRAFT CFD® Overview: The CRAFT CFD® code is a state-of-the-art, three dimensional, structured grid Navier-Stokes code with a multiphase formulation which allows for generalized three-phase mixture of gas, bulk liquid, and a dense dispersed phase of droplets or solid particles. CRUNCH CFD® Overview: CRUNCH CFD® is a general multi-element unstructured grid Navier-Stokes code for complex geometries and multi-body problems. Its edge-based data structure permits the use of various element types for increased flexibility in geometric modeling. CRISP CFD® Overview: CRISP CFD® has been developed to work in conjunction with unstructured grid flow solvers to provide grid independent solutions through adaptive refinement and coarsening. These methods have also been employed in dynamic mesh simulations featuring multi-body motion. For information on these codes, please contact info@craft-tech.com |
