Phys. Rev. Lett. 99, 075003 (2007) [4 pages]Momentum Transport from Current-Driven Reconnection in the Reversed Field PinchReceived 15 June 2006; published 16 August 2007 We calculate momentum transport from tearing fluctuations in a reversed field pinch with sheared flow, considering both the effect of a single tearing mode (through quasilinear theory and MHD computation) and multiple tearing modes (through nonlinear MHD computation). A single tearing mode transports momentum, via Maxwell and Reynolds stresses, more rapidly than classical viscous forces. Moreover, the transport is enhanced by nonlinear coupling of multiple modes. © 2007 The American Physical Society URL:
