S1-4 · On the link between edge sheard flows and turbulence in fusion plasmas C. Hidalgo, A. Alonso, J.L. de Pablos, M.A. Pedosa, E. Sánchez Abstract: The development of new diagnostic and analysis tools is spawning a new era in fusion plasma research to unravel the global pictur connecting transport and flows. Properties of turbulent transport in fusion plasmas can not be understood without considering the coupling with sheard flows. The link between edge sheard flows and turbulence has been investigated in the plasma edge region of stellarator (TJ-II) and tokamak (JET) plasmas. The fact that different quadratic terms in fluctuating velocities change during edge sheard flow generation means that shear flow physics involves 3-D physics phenomena in which both perpendicular and parallel dynamics are involved. A new strategy has been recently applied to plasma physics to quantify the local energy transfer between flows and turbulence by computing the production term. Experimental results show that turbulance can act as an energy sink and energy source for the mean flow near the shear layer.
