The flow field studied was eight strongly impinging, radially injected jets,into a non-swirling mainstream flow in a cylindrical duct. Our previous paper(Heat Mass Transf. (2020) 56:2285-2302), showed that asymmetry in the solutionis very likely to be an indication of the flow unsteadiness. Also, if the flowis asymmetric, even a time dependent flow solver would not represent the flowcorrectly if the computational domain is less than the complete cylindricalduct. Thus, the current numerical and topological study was conducted in a 360degree (complete cylindrical duct) computational domain using a time dependentUnsteady Reynolds-Averaged Navier-Stokes URANS code. Results of this studyconfirm that the flow of strongly impinging jets is unsteady and asymmetricafter the establishment of a regular flow pattern. The asymmetry appears to becyclic at a frequency of < 2 Hz. Also, the computational fluid dynamics (CFD)results agree with the rules of topological analysis from applied mathematics.
