Rotating machinery

OUR expertise

Many industrial processes involve rotating machines: mixers, ship propulsion, cooling of electronic components, turbo-reactors or even wind turbines … The CFD numerical simulation makes it possible to understand the behavior of these different and complex processes by means of and adapated methodologies :

MRF : multi refrence frame.

AMI : arbitrary mesh interface (slidding mesh).

Overset mesh.

We propose to adapt our calculation and modeling strategy to your needs by choosing the most appropriate calculation tool and the most efficient methodology.

Examples of studies involving rotating machines

Numerical simulation of a wind turbine

  • The implementation of numerical models for wind turbines (whether vertical or horizontal axis) allows the engineer to predict the characteristics of the machine such as power or efficiency (cp(lambda) and this for modelizations of scale 1. Fine studies can also be conducted at the level of the blade design to optimize its performance.

  • Calculation carried out using OpenFOAM

Tank mixing process

  • Mixers are stirring devices commonly used in industry (and especially by the chemical industry). For this type of application, numerical simulation makes it possible, for example, to characterize the performance of the mixer (homogeneity of the mixture, average travel time, mixing time, dead zone, etc.).

  • Calculations carried out using OpenFOAM.

Propeller sizing and shape optimization

    • Numerical simulation is a major addition to the calculation of the Kt and Kq curves of a propeller or the prediction of the cavitation phenomenon. Indeed, the performance curves (Kt and Kq) are not always available and there are several numerical methods to calculate them (MRF, Sliding mesh or even overset mesh). Moreover CFD can also be very helpful to optimize the blade design and to understand the turbulence structures generated by the propeller and its interaction with the hull.

  • Calculations carried out under OpenFOAM.
