Computational wind engineering using finite element package ADINA

Abstract

Design of tall and long span structures is governed by the wind forces. Inadequate research in the field of wind dynamics has forced engineers to rely on design codes or wind tunnel tests for sufficient data. The present work uses a computational wind dynamics method to compare the coefficient of pressure (Cp) for the different aerodynamic shapes. ADINA, a finite element package, contains an inbuilt turbulence model which will be used to construct four different shapes for comparison. Results are verified with the experimental and simulation data. The effect of increase in the Reynolds number on the flow has been studied. Graphs for the pressure, velocity and turbulence energy distribution have been developed to assist the engineers in design.
