Software Partnership

Reaction Design will provide a free version of its CHEMKIN-CFD that has been optimized to work with ANSYS FLUENT to ANSYS customers. Traditional computational fluid dynamics (CFD) algorithms achieve convergence of all the momentum, energy, species and mass conservation equations in a 3-D model through iteration, which can be cumbersome and time-consuming. CHEMKIN-CFD, which is specifically designed to handle stiff gas-phase and gas-surface chemistry, employs a proprietary solver to speed up simulation without sacrificing accuracy. It solves species and energy conservation equations in a closely coupled manner for both transient and steady-state problems. Within a flow simulation, this version of CHEMKIN-CFD solves coupled conservation equations at every cell (or grid point), at every iteration, and at every time-step. ANSYS FLUENT software then performs transport calculations over all grid points, with an option to use transport properties from CHEMKIN-CFD.
