Importance of Simulation in Engineering Design

Short Youtube video

He explains in an interview the use of FloEFD for his engineering consultancy.

Power Electronics Cooling Calculation at Room Level

recorded webinar

The meaning of the Room Level is explained. The working point of the fan can be evaluated using CFD calculations. The heat transfer is not calculated for reasons of cost
and because the electrical losses are insufficiently known. The ventilation of the components is evaluated using the streamlines, the flow vectors and the pressure distribution.

The frequency converter and the IGBT chips need cooling, The value of the thermal resistance of the Thermal Interface
Materials influences the results. Set-up a transient case for low frequencies.

Parametric Study of an IGBT Cold Plate Geometry in a
Thermal Simulation**

recorded during the Integrated Electrical Solutions Forum 2014 in Munich. The heat sink consists of a water-cooled plate made of aluminum. A parameter variation analysis of the water cooling was carried out with FloEFD for Catia in order to find out the best geometry parameters such as size, number and height of the cooling fins.

Winding Parameter Variations for the Cooling of an Electrical Motor

recorded during the Integrated Electrical Solutions Forum 2014 in Munich. Different winding configurations of the motor. Bar windings are simulated with their copper and insulation layers whereas the composite wire winding is simulated by assuming equivalent thermal conductivities.

CFD Design of a shaft-mounted radial fan for the cooling of an electrical motor

recorded for the "Realize live Europe 2022" conference in Berlin. The examined 120 kW asynchronous motor has a completely closed cooling system. The fan is mounted on the shaft, it uses the rotation of the shaft and therefore does not need an external motor. To design the fan, it is important to fully model the fan with its blades and rotation. We will show the different methods for simulating rotation in Simcenter FloEFD. When the design of the fan is complete, a fan curve (volume flow versus pressure) can be drawn by varying the motor's flow resistance. For the detailed flow design of the machine, it is sufficient to simulate the fan with its curve.
