Numerical and Experimental Models of Load on Buldings from the Effects of the Atmospheric Wind

Abstract:

The paper describes two different approaches of the solution of benchmark solution of bluff aerodynamic, which is the solution of wind pressures upon the cube exposed to the effects of air flow field. Two tasks are discussed in this article. One has the flow field with the constant wind velocity and low turbulence intensity, while the second one simulates the flow in the simulated Atmospheric Boundary Layer. Physical modelling is carried out at the wind tunnel of the Institute of Theoretical and Applied Mechanics in Telč. Numerical modelling is carried out at the Department of mechanics, Faculty of Civil Engineering, Technical University of Ostrava. Commercial code Ansys - Fluent has been used for the calculation.
