METHODS OF COMPUTER MODELING IN PROBLEMS OF HIGH-RISE BUILDINGS AERODYNAMICS
Abstract
The article formulates several provisions for principal possibility of application of computational aerodynamics methods for determination of wind effects on tall buildings with complex geometric shapes. Formulated urgency of problem in framework of control volumes method, analysis of atmospheric turbulence models that are implemented in modern software systems of computer simulation. Recommendations on construction of buildings computer models, simulation of wind regimes of fields around buildings and formulate a set of theses for a correct choice of boundary and initial conditions of simulation. Computer modeling, addition to developed software modules that are allowed to display main features of separated turbulent flow in the flow around high-rise buildings and to determine the value of the aerodynamic forces and moments that act on them.Key words: aerodynamics, high-rise buildings, wind tunnel, computational aerodynamics, geometric shape.
