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. […]

Turbulent Combustion Modeling

Dr. William Calhoon from our CRAFT Tech office in Huntsville, AL has recently developed an advanced, computationally efficient turbulent combustion model for large-eddy simulation (LES) of aircraft and power system gas turbine combustors.  This new formulation is designed to capture local flame extinction and global flame blow-out effects, thereby enabling improved predictions of lean blow-out […]

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 […]
