Superfluid turbulence in helium II has beenstudied experimentally and theoretically for many years. Differenttheories have been used to elucidate different aspects of turbulentvortex motion. All models, except for the microscopically accurate GP model thatcan not be used to study large-scale dynamics, are largelyphenomenological. Our research will allow a cross-fertilisation between these theories and will replace mostly phenomenological models withrigorously derived stochastic equations.

氦II中的超氟湍流在实验和理论上已经在很多年中被研究。不同的理论已被用来阐明湍流运动的不同方面。除了不可用于研究大规模动力学的显微精确的GP模型外，所有模型均已很大。我们的研究将允许这些理论之间进行交叉灌输，并将用辅助衍生的随机方程替代现象学模型。
