A thermostat closure for point vortices

Dubinkina, Svetlana; Frank, Jason; Leimkuhler, Ben

Using the point vortex flow on a disc as a prototype, we present a closure for incompressible ideal fluid flow in the form of a generalized thermostating device. The thermostat can model either an infinite or finite reservoir. The thermostat variables are stochastically forced. Numerical experiments are in excellent agreement with the two-scale simulations of Bühler (Phys. Fluids, 2002).
