Simulation of flow in an idealised city using various CFD codes
In the framework of the COST 732 action, several teams run models to verify the proposed Best Practice Guideline (Franke et al., 2007). The data set concerns the Mock Urban Setting Test (MUST) experiment, where wind field and dispersion measurements were conducted for an array of obstacles as a full-scale experiment, as well as in a wind tunnel. The pollutant transport research group at the Department of Fluid Mechanics of the BME started simulations of flow within this idealised city using two commercial CFD codes, FLUENT and MISKAM. The paper presents results of the flow simulations in the 0 degree MUST case through velocity profiles, contour plots and validation metrics.
