Outline of Final Research Achievements

The aim of this research project is to mathematically formulate and analyze the interaction of thin vortex structures within fluids. Specifically, we utilize nonlinear partial differential equations describing the motion of vortex filaments and investigate the existence and stability of solutions which correspond to particular motion patterns. In this regard, we were able to publish 2 research papers (1 accepted, 1 submitted). Furthermore, we investigated the motion pattern of three coaxial circular vortex filaments and obtained numerical evidence which suggests the existence of interesting motion patterns.
