Mathematical modelling of an unstable bent flow using the selective frequency damping method

11/05/2020 ∙ by Alexander V. Proskurin, et al. ∙ 0

The selective frequency damping method was applied to a bent flow. The method was used in an adaptive formulation. The most dangerous frequency was determined by solving an eigenvalue problem. It was found that one of the patterns, steady-state or pulsating, may exist at some relatively high Reynolds numbers. The periodic flow occurs due to the instability of the steady-state flow. This numerical method is easy to use but requires a great deal of time for calculations.
