Aeroelasticity and Fluid-Structure-Interaction Wading Simulation for Off-Road Vehicles Vehicle wading refers to situations where vehicles traverse through Wing and Spoiler Design water at different speed. One of the major challenge is computing The deformation and dynamic fl utter of aircraft wings or racecar the inertial fi eld of the vehicle while wading. In cooperation with spoilers can be analyzed using combinations of suitable structural Jaguar-Landrover, Fraunhofer has developed a new method of mechanics and CFD codes. Customers from aircraft industry and co-simulation between CFD (STAR-CCM+) and MBS (SIMPACK). leading Formula1 teams have integrated coupled Fluent-Nastran or Abaqus-OpenFOAM solutions in their daily development processes. Thermal and Vibration Loads in Turbomachinery Hydraulic Pump Layout In cooperation with Gdansk University, Bandak Engineering Thermal Loads on Ceramic Impeller developed a new type of axial pumps with cam-driven In order to increase the effi ciency of micro gas turbines by higher commutation units (PWK pumps). An Abaqus-Fluent combination gas temperatures, new material concepts for the high temperature was used to determine the optimal layout for the different loaded parts are required. Fraunhofer has developed a new chambers and to minimize noise and vibration of these pumps. impeller concept (using a thermally coupled FINE / Turbo – Abaqus solution) and applied it for rotation speeds up to 120,000 / min.

Automotive Thermal Management Life-Time Estimation of Turbine Blades To estimate the long term behavior and high cycle fatigue in The calculation of the thermal behavior of automotive vehicles operation, the periodic pressure oscillations of the fl ow and the has to take into account the full complexity of a vehicle’s excited oscillations of the turbine blades have to be known. A geometry and heat transport phenomena including convection, transient coupling of fl uid pressure and blade deformation delivers radiation and conduction in fl uids and solid bodies. For this task, stress oscillations and thus the basis of fatigue analyses. original equipment manufacturers (OEMs) use a combination of TAITherm / RadTherm with STAR-CCM+ or inhouse CFD solvers.

Vehicle Dynamics and Non-Linear Component Behavior Cooling of a 3-Phase Transformer The thermal performance of an oil-immersed power transformer Driving over Obstacles is governed by the oil fl ow for the heat transfer generated in the Various automotive OEMs use a combination of Abaqus and windings and core toward the tank and the surrounding air. A MSC.Adams to model the non-linear behavior of single critical JMAG-Fluent coupling has been used to detect the local hot spots. components and their interaction with the complete vehicle system. Applications with strong dependency on accuracy, like e.g. Electric Arc in Switching Devices fatigue life calculations, benefi t from co-simulation. Switching arcs can be modeled using ANSYS EMAG to solve the magnetic fi eld problem and Fluent to solve the fl uid dynamics problem – coupled in volume through MpCCI.
