Numerical Analysis of the Effects of Wind on Building Structures
ABSTRACT The paper deals with the theoretical foundations of laminar and turbulent fluid flows in a boundary layer and the effects of wind on constructions. The application section describes the flow of compressible Newtonian fluid as a system of partial differential equations (the Navier-Stokes equation) and solves these equations using FEM at each time step. Simplifying a 3D task to a plane problem and ignoring vorticity allows for the formulation of a wind flow on an open terrain and the effects of wind on a barrier. Two approaches to the numerical solution of wind flows are presented: one involves the Fluent commercial program to obtain the velocity field and pressure at a constant wind speed in an inlet region, and the other approach involves the development of the SIXIS specific software program for the purpose of this thesis, which modifies the wind velocity profile according to EN 1994-1-4. The results obtained - velocity fields around obstacles and the wind pressure coefficients on a barrier are processed and compared in a table.
