Simulation of microtearing turbulence in NSTX
Thermal energy confinement times in NSTX dimensionless parameter scans increase with decreasing collisionality. While ion thermal transport is neoclassical, the source of anomalous electron thermal transport in these discharges remains unclear, leading to considerable uncertainty when extrapolating to future ST devices at much lower collisionality. Linear gyrokinetic simulations find microteari...
متن کاملStudy of Parameters Affecting Separation Bubble Size in High Speed Flows using k-ω Turbulence Model
Shock waves generated at different parts of vehicle interact with the boundary layer over the surface at high Mach flows. The adverse pressure gradient across strong shock wave causes the flow to separate and peak loads are generated at separation and reattachment points. The size of separation bubble in the shock boundary layer interaction flows depends on various parameters. Reynolds-averaged...

متن کاملComparison of edge turbulence imaging at two different
This paper describes 2-D imaging measurements of plasma turbulence made in the scrape-off layer of the Alcator C-Mod tokamak simultaneously at two different poloidal locations, one near the outer midplane and the other near the divertor X-point region. These images were made with radial and poloidal resolution using two gas puff imaging (GPI) diagnostics, which were not directly connected along...
متن کاملHigh-speed AFM imaging.
Proteins are dynamic in nature and function at the single molecule level. To achieve a straightforward and in-depth understanding of their underlying functional mechanism, we need to directly observe protein molecules at work at high resolution, without the use of protein-attached markers. To realize such objectives, high-speed atomic force microscopy (HS-AFM) has been developed and recently it...
