Other focus areas: - CFD in: Energy Engineering, Biomedical Engineering, - Computational methods applied in: Material science & engineering

Description

Our team has had many years of experience in developing and employing computer models to complex systems for simulations, where the details of flow, stresses, and deformation can be obtained.

The detailed information may be either solely important for observation of localization effects, or important in obtaining averaged values. Some focus areas of our team within the last ten years have been related to:

  • energy technology using fluidized beds,
  • biomedical engineering studying blood flows in arteries,
  • porous materials and applications in engineering.

The purpose of our research is to find proper answers to practical problems as depicted above using computer modeling and simulations.

How are we connected to SIM-platform?

The idea behind SIM-platform is to create a strong base for multidisciplinary computational research closely linked to business field. Real-time simulations and their role in industry and advanced technologies is an important objective sought in SIM-platform.

Our role in the SIM-platform is focused on CFD simulations that can provide necessary hydrodynamic information for real-time multibody dynamics simulations based on fluid-solid interaction results.

Objectives of research in SIM-platform

Certain objectives are sought in our research in association with the SIM-platform. The following aims are set in research:

1. Surface tractions or stresses exerted from fluid on solid surfaces are obtained from CFD for certain mechanical parts involved in machinery. The key point in real-time simulations is the speed of calculations which has to be quick enough to move forward simultaneously with the multibody dynamics simulations used in the computer codes employed in simulators.

Since CFD simulations are not usually as fast as needed in machinery simulators, the objective here will be to present a combined method in which CFD results are used offline in connection to analytical methods and other mathematical tools such as neural networks. By means of such combined methods, one can quickly obtain the forces/torques exerted by a fluid on a solid piece that is partially or fully immersed in a fluid.

2. In addition to scientific values of the objectives mentioned in 1, the second important objective is the commercialization of the results by various ways. Obviously, there is a great interest scientifically and commercially in accelerated calculations related to fluid-solid interaction in real-time simulations.

Schematic demonstration

The above-mentioned objectives can be summarized in the following schematic chart:
