Turbulent Combustion Modeling Featured on Ansys Guest Blog

CRAFT Tech was recently tasked by its customers to develop an LES turbulence — chemistry interaction subgrid model to capture local extinction and blow-out effects that satisfied the following requirements: the model should be portable to commercial CFD flow solvers, and the model should be tractable for routine application within a system design cycle environment. […]

Six degree-of-freedom (6DOF) unsteady CFD simulation of flat plate moving through domain using cell cutting

Rarefied Flow Simulation With 6DOF Motion

CRAFT Tech has been involved in rarefied flow simulation for over a decade. Our most recent work has pushed the state-of-the art to include six degree-of-freedom (6DOF) motion. Utilizing our in-house Direct Simulation Monte Carlo (DSMC) solver, we can now perform simulations of unsteady rarefied flow phenomena and their subsequent effect on objects. Rather than […]
