Superfluid 3 He-B vortex simulations inside a rotating cylinder

We study numerically vortex dynamics in superfluid 3He-B by solving the full Biot-Savart equations inside a rotating cylinder. The initial vortex configu-ration seems to have an essential role whether the growth process starts or not. The growth process is, at least at the early stages of simulations, mostly governed by the reconnections with cylinder boundary. In order to see a large increase in vortex density one should go below 0.5Tc in temperature, somewhat lower than what is observed in the experiments. PACS numbers: 47.32, 67.57. 1
