Abstract
The structural design considerations of a power station chimney are mainly governed by the effect of the wind loads. Wind tunnel studies become important to measure wind loads on the models of the chimney. It is very important to take the effect of interference in design of high rise structure for the serviceability purpose. It takes into account the variation of the mean wind velocity and turbulence parameters with height above the ground level. For the calculation of the wind loads and there effects; extensive wind tunnel testing is required. CFD offers a very powerful alternative to predict the wind related phenomena on chimneys or different kind of structures. A software package, FLUENT-14 (ANSYS 14.0) was used for CFD analysis. FLUENT-14 is a general CFD code based on the finite volume method and an algebraic multi-grid coupled solver.
