In this paper we describe an extension of a recently developed lattice Boltzmann method for solving the advection–diffusion equation. Our proposed approach allows to couple grids of different grid resolutions and includes a staggered timestepping scheme, interpolations in space and time and finally a scaling step ensuring the continuity of the desired(More)
The UNO predicts that in 2030 over 60% of the world population will live in urban environments. This percentage will increase to up to 70% in the year 2050. With that said, more than ever it is essential that we protect the living conditions in inner-urban regions. In this regard the air quality is of particular importance. The microclimatic implications of(More)
Since the NVIDIA Compute Unified Device Architecture (CUDA) SDK has been released, multiple publications have demonstrated that simulations in the field of Computational Fluid Dynamics (CFD) may substantially benefit from the utilization of General Purpose Graphics Processing Units (GPGPU), which offer a high performance vs. price ratio compared to(More)
