جریان سیال در اطراف دودکش با رگه های مارپیچ – کامسول

Wind strakes on a chimney impede the uniform detachment along the height of the chimney, which can induce vibrations and eventually lead to fatigue at the footing of the chimney. A stationary turbulent flow simulation is computed for a chimney with strakes mounted on a factory building. The results of the stationary solution are used as initial conditions for a transient turbulent flow simulation to assess the effect of the strakes on periodic detachment.
