|Title:||BOUNDARY TREATMENT IN WIND FLOW SIMULATION AROUND BUILDINGS|
|Keywords:||CIVIL ENGINEERING;BOUNDARY TREATMENT;WIND FLOW SIMULATION;BUILDINGS|
|Abstract:||The development of modern material and construction techniques has resulted in the emergence of a new generation of structures that are often, to a degree unknown in the past, remarkably flexible, low in damping, and light in weight. Such structures generally exihibit an increased suspectibility to the action of wind accordingly it has become necessary to develop tools enabling the designer to estimate wind effects with a higher degree of refinement than was previously required. This dissertation presents a k-E model for the simulation of wind flow around building _Constant values of turbulence kinetic energy (k) and rate of dissipation of turbulence kinetic energy (e) are tried in the present work. Finite difference method is used to discretize the equations The size of the domain is very important in the simulation work, therefore three different domain sizes are taken for the same mesh size. Mesh sizes used for simulation work are 0.5m and 0.33m. A comparative evaluation of simulation based on k-c and Prandtl's mixing length hypothesis is also presented here. Pressure coefficient are also calculated at the first and second grid live near building.|
