Chimneys are tall structures used in power plants, chemical units and other manufacturing units. The chimney structures are subjected to high wind loads which may cause lateral deformation and increased base shear. The objective of current research is to investigate the external air flow on high rise chimney structure using techniques of Computational Fluid Dynamics. The modelling and simulation of chimney is conducted using ANSYS simulation package. The fluid flow characteristics i.e. pressure, velocity and drag forces are determined from CFD analysis of chimney. The effect of wind load on chimney structure is evaluated using velocity plot, pressure plot and eddy dissipation. The regions of high pressure and velocity fields are determined from CFD analysis. The variation of pressure and velocity with respect to height is also investigated.
