Karim Segond
Consulting Engineer for Fluid Dynamics and Cooling

Karim Segond was born in 1973 in Toulouse, France. After obtaining the high school diploma (baccalauréat scientifique), he began studying mechanical engineering at university in Toulouse. In 1996, he left the region in order to continue his studies at the Technical University of Berlin where he obtained the Master in Mechanical Engineering in 2000. During his studies, Karim worked at Siemens Large Drives in Berlin, where his main tasks were the 3D thermal and flow calculations for a synchronous motor with turbo rotor. He was supervised by Mr. Zwarg.

After his studies, Karim moved to the German-speaking part of Switzerland in order to work at Alstom Power in Baden. He worked as an aerodynamics engineer on the development of new low-pressure steam turbines, together with the vibration and stress engineers and the draughtsmen. On a daily basis, he successfully used the Alstom company CFD codes. He also improved the design process using the 6sigma method. The toughest challenge of his carrier was certainly  the wet steam calculations for a low-pressure steam turbine.

In 2007 he moved to Alstom power plant construction, where he worked in the office in Baden as well as on combined cycle power plant construction sites in England. He gained experience in the fields of management, tendering as well as commissioning and operation of the combined cycle power plant.

Since 2011 Karim has been working as a consultant for cooling calculations of electrical equipment like Electrical Machines, Power Electronics and Electronics. He mostly works from his office in Berlin but he can also work at the customer’s. His first task was performing 3D thermal and flow calculations for a electrical motor as an external contractor at ABB Minerals in Switzerland. It was a slow rotating pole salient synchronous ring motor; the calculations were performed with the CFD pre- and post-processor and solver CFX in combination with Ansys Meshing and Ansys Design Modeler.

After this task, he benchmarked the different CFD tools and he clearly preferred to work with software based on cartesian mesh like FloEFD, FloTHERM, TransAT or Solidworks Flow Simulation. These tools allow to set up easy and fast heat transfer cases; the resulting costs are correspondingly low. By using these tools Mr. Segond offers a distinct competitive advantage to his customers over the ones still using older tools.

Besides the electrical machines, Karim is investigating the thermal management of the power electronics components used to drive such large engines. Here CFD can be leveraged to optimize the design and ensure the best possible cooling for the components. He has also turned his attention to the overall cooling of a system: such cooling systems are too big and too complex to simulate with 3D CFD software. Therefore it is necessary to analyze them using a thermal and fluid flow network that is modeled in a 1D CFD-tool such as FloMASTER. This combined solution enables Karim to provide the qualities of both tools and provide the ultimate cooling solution to his customers.

Karim has always had a strong interest in foreign cultures and has visited numerous countries. He has spent the last fifteen years in Germany, Switzerland and England, where he has always shown good integration capabilities. He thinks truly global, is open to customers all over Europe and has private as well as business contacts throughout Europe, India and South East Asia. He has very good oral and written communication skills in German, English and French. His interests are traveling, visiting art museums, snowboarding, swimming, fitness and biking.
