Abstract:
In order to analyze the regular vortex shedding phenomena of high-rise building model observed by wind tunnel test, authors first established a parallel computing platform using the general software of computational fluid dynamics CFX and local area network with the message passing interface(MPI)network parallel environments, then, simulated a 3-D unsteady wind field around high-rise building while the simulation couldn't be settled by a single computer. The vortex shedding phenomenawere captured by numerical simulation with shear stress transport(SST)turbulence model. The comparison between numerical simulation and wind tunnel test was given. The results show that the varying rules of surface wind pressure on the high-rise building are acquired through 3-D unsteady simulation, and 3-D unsteady simulation's results are used to predict the wind field more truly than 3-D steady and 2-D unsteady simulations' results.
