Modelizacion numerica de cargas de viento sobre un tanque de almacenamiento de combustible

Abstract : One of the structural problems detected on oil storage tanks is wind-induced buckling failure. Accurate estimation of wind loads is important for the evaluation of structural integrity of these facilities. In this context, a numerical study is presented, employing the Reynolds Averaging Navier Stokes (RANS) methodology for the prediction of wind-induced pressure loads over a cylindrical storage tank. Mean pressure distributions obtained through RANS turbulence models, are compared with atmospheric boundary layer wind tunnel experimental measurements for a tank with both closed planar and conical roof shapes. Different aspect ratios and Reynolds numbers representative of the conditions present in oil storage tanks exposed to the atmosphere are considered. Details regarding both the employed numerical methodology and the computer implementation are discussed and presented. Finally, the conclusions obtained based on the present numerical study are introduced.
