Fluid Flow Around a Chimney with Helical Strakes

Application ID: 103921


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.

This model example illustrates applications of this type that would nominally be built using the following products:
