Flow simulation - Import export

In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels and turbines and optimise existing systems for performance, energy efficiency and noise emissions. We also develop complete systems of wheels with power units. Our range of tests includes suction operation, pressure operation and also unpressurised measurements. Revolutions up to 40,000 r/min and diameters of up to 250mm are possible. In our prototype department, we are able to simulate or modify the environmental circumstances of the fan wheels or turbines, thus achieving optimal operational conditions. Furthermore, we carry out mould-flow analysis, use ANSYS from external partners for the flow simulation and establish the fault probability and fault effect with FPFEs. New: Development of blower systems and optimization of ventilation systems.

Challenging, customer-specific mixing technology solutions can be numerically simulated as early as during the planning phase, and the results analyzed. This means increased design confidence, high-quality solutions and, as a result, reduced project durations and costs. Our experts from THINK Fluid Dynamix® are specialists in the application of numerical techniques such as flow simulation in real time and artificial intelligence methods for automated optimization. This enables processes, such as stirring and homogenization, to be analyzed more accurately under consideration of all applicable process parameters, and complex tasks to be processed far more efficiently. These methods set entirely new standards in terms of design reliability and efficiency. Allow us to contribute to your success!

RWIND is a program (digital wind tunnel) for the numerical simulation of wind flows around any building geometries with determination of the wind loads on their surfaces. RWIND is available as a Basic and Pro version.

Actran AeroAcoustics Predicting the noise generated by complex flows Actran AeroAcoustics is a finite element based acoustic solver for predicting the noise generated by turbulent flows. Actran AeroAcoustics recovers aerodynamic noise sources from flow simulations performed with commercial CFD codes such as Fluent™, Star-CD™, StarCCM+™ or Powerflow™. The complete simulation procedure involves three steps: An unsteady flow simulation is performed by the CFD code. At each time step, the CFD solution (velocity, density and pressure fields) is stored in its own native format or in the Ensight™ format. Actran AeroAcoustics computes the aero-acoustic noise sources from the CFD results produced in step 1. This involves translating results from the time to the frequency domain and interpolating them from the CFD to the acoustic mesh. Maps of the aero-acoustic sources produced at this stage are in themselves useful results which can be used to identify the most effective sources. The radiated acoustic field radiated is then computed. This produces a wide set of relevant results: acoustic pressure, velocity or intensity maps, frequency response functions of various local (pressure) or global (power) quantities. This multi-step strategy offers several advantages: (1) Each part of the work can be done independently by different engineers, departments or even companies with different responsibilities or skills. (2) A single CFD simulation can feed different acoustic simulations (e.g. with different acoustic treatments). (3) The acoustic mesh does not need to be refined where the aerodynamic structures are small (for instance in the boundary layers). Actran AeroAcoustics offers high performance solvers and parallel processing features and is fully integrated in Actran VI. Actran AeroAcoustics can be combined with Actran VibroAcoustics in order to address aero-vibro-acoustic challenges. Target applications: Air conditioning modules (HVAC). Side mirror noise. Airframe noise (landing gear, trailing edge). Air distribution systems.
