Summary on Grant Application Form
Turbulence in classical fluids is important and challenging both for theory and for many practical applications. The research aims to understand how classical turbulence is modified in a superfluid, in which flow is severely restricted by quantum conditions associated with the quantization of angular momentum.At higher temperatures, superfluids exhibit two-fluid behaviour, a normal fluid coexisting with the superfluid component in which the quantum effects are important. There is already strong evidence that at these temperatures turbulent structures on large length scales can be very similar to their classical counterparts, although dissipative processes acting on small scales are very different. It is suspected that a similar situation exists at very low temperatures, where the normal fluid is absent, and where simple mechanisms for the decay of the turbulence have disappeared. Our programme seeks to provide experimental evidence relating to these low temperatures, at which the fundamental behaviour of very pure forms of quantum turbulence ought to be observable, the turbulence being generated by either a steadily moving grid or an oscillating grid, the case of a steadily moving grid being almost certainly easier to interpret. Quantum turbulence is of great intrinsic interest, and its study could lead to a better understanding of classical turbulence. The proposed calorimetric technique complements an existing programme based on ion trapping and has become possible through collaboration with the University of Florida. The present proposal is to bring the Florida team leader, Professor Gary Ihas, to work directly on the project in Lancaster during his forthcoming sabbatical leave.
