Numerical (CFD) investigation of flow processes

Our competence is primarily to provide numerical modelling of flow conditions in fluid engineering equipment and special spaces, as well as numerical investigation of heat exchange processes in thermal engineering equipment using computational fluid dynamics (CFD). This allows us to study industrial processes more cost-effectively and faster in accordance with today’s requirements by modelling various flow and thermal engineering processes, with which we can support industrial actors in achieving their research and industrial goals. Tests can provide data that is difficult to measure or cannot be measured due to physical limitations. The simulations allow coupled studies from chemical reactions (combustion, mixing) to mechanical studies (static or dynamic loads).

Competencies

• We perform complex investigations by numerical modeling of flow and thermal engineering processes in industrial equipment and machines, as well as in special spaces (using commercial or own codes).
• With the help of the tests, we can determine the location for the measuring instruments to be placed in the interior and the typical flow conditions, as well as formulate proposals for the operation or further development of the machines and equipment.
• With our research and teaching experience, we examine flow and heat engineering systems with a complex approach, which we can provide to those interested in the form of consultation or training at different levels.
