Fluid Dynamics

Understanding the underlying physics is way more important than understanding how the tool for simulating the physics is used.

At Creo, we engage in many different projects regarding aerodynamics, thermodynamics, aero acoustics, fluid structure interactions etc., and we often use advanced tools such as CFD for simulating perturbations and their propagation. But not always. Sometimes a problem can be as easily solved or analyzed using engineering judgment or through methods by hand.

But when using tools such as CFD, we always look at the simulation result as something much more than what the output is in numbers and pictures. We see the positive environmental impact we have generated through decreasing the fuel consumption of a car, airplane or perhaps a gas-turbine.

We see the consumer enjoy walking past a wind power turbine without being disturbed by any aerodynamically induced noise. We see train passengers enjoying the comfortable climate from the inside of the passenger compartment. And we see our satisfied customers realizing that they did the right thing when asking us for support.

We are fluent in most commercial software’s and we run both transient and steady state simulations every day. Due to the fact that we engage in systems for active control of both noise and aerodynamic separation, we prefer to use the open source code OpenFOAM as we then can access and alter the source code to fit our specific purposes. As one of few companies, we also have the capability to run simulations in Edge, a solver developed by the Swedish Defence Research Agency (visit the FOI website
