3d fluid simulationCopyright: EBC
Achieving knowledge of the behaviour of air flows in buildings or system components is essential for powerful and efficient operation. Computational fluid dynamics (CFD) has become an indispensable tool alongside experimental investigation due to constantly improved methods.
Nowadays, the wide range of applications for flow simulation makes it possible to make a considerable contribution to development progress in building and room air conditioning technology as well as in the fields of aerospace, power plant and vehicle technology.
The various simulation methods are optimally applied and adapted for the various research topics at the Institute for Energy Efficient Buildings and Indoor Climate. The application ranges from the component optimization to the simulation of room air flows and the calculation of complete systems and buildings. The complexity of the investigation can be increased from simple laminar pipe flow to multiphase flow or flow acoustic prediction.
The widely used simulation package ANSYS CFX or Fluent is mostly used as software. In addition, smoke/fire simulations can also be carried out using special methods using FDS or couplings to the 1D energy system simulation. In addition to the high-resolution classical Reynolds-averaged (RANS, unsteady RANS) and scale resolution turbulence methods (LES, SBES, DES), coarse-grid methods are also used for real-time simulations.
