Description

Peter Nielsen was Co-chair at the workshop 4 at The 9 International Symposium on Heating, Ventilation and Air Conditioning (ISHVAC). It is known from experiments and simulations that low Reynolds' number effects may take place in room air flow. We know that this type of flow is difficult, to predict in details by CFD due to limitations of available turbulence models in connections with RANS equations, limitations of computer capacity and limitations in other types of methods as e.g. the use of LES. Errors due to choice of numerical methods, choice of the right physical model of the engineering problem you solve, choice of relevant boundary conditions and errors due to user's experience are also a part of relevant problems in doing CFD predictions. The purpose of this unique workshop is to focus on errors existing in CFD simulations, especially in connection with low turbulent flow, and discuss what we can do, using a simple method. We present a simple CFD problem (with no benchmark or experimental data for comparison) for all participants of the workshop to simulate using well-known and widely used commercial CFD software. We ask you to send your CFD results to us, and we shall consolidate all the results, and present in the workshop.
