| description: | The proposed research is focused on the theoretical and numerical study of starting vortex flows produced in vortex generators. In the framework of this research we indent to simulate numerically a general case with taking into account different methods of vortex ring-like flow generation and variability of generator parameters (e. g. exit diameter, the shape of the nozzle exit, etc.). The primary goals of this investigation are the discovery of general principles for optimal vortex flow formation. Recent studies of the vortex formation in biological fluid also show that these principles can be used in broad range of biological systems including cardiac flows. On the basis of the direct numerical simulation we intend to develop earlier reported by applicant model for formation of "optimal" vortex ring on the most common case of observed starting vortex flows including biologically-relevant flows. Finally we intend to validate the constructed model on the basis of experimental data from laboratory experiments and from in vivo animal measurements reported in literature. This research serves a dual role, both as an applied study and as a fundamental investigation of fluid mechanics. The outcome of the proposed research can provide development of a robust framework to facilitate the discovery of general design principles for effective fluid transport in engineering technologies and biological systems. |
