Fast wave poloidal flow generation at the plasma edge of a tokamak is studied with a one‐dimensional slab model. In the absence of mode conversion, the poloidal flow can be generated by a spatial change of plasma velocity and current density profil

A single-equation model of long-wavelength drift waves has been used to study the behavior of turbulent plasma fluctuations in the presence of sheared flow. These waves, which have a real frequency, are calculated using a time-evolution algorithm tha

The results of detailed numerical studies of phenomena in negative compressibility turbulence with sheared perpendicular (i.e., poloidal) flow are presented. The turbulence model is based on the parallel ion flow gradient instability, a representativ

A simple model of long‐wavelength drift waves is used to study the way in which a radial electric‐field profile influences the growth and saturation of turbulence. For a fixed external field, the effect of curvature (∂2Er/∂r2) dominates that

A simple, paradigmatic model of long‐wavelength drift wave turbulence in the presence of a sheared poloidal flow is analyzed in detail. Linear theory predicts that velocity shear induces a strong stabilizing effect by shifting the eigenmode away fr

Magnetic perturbations caused by external field errors are an important consideration in both the current operation and future design of reversed‐field pinch (RFP) devices. Recently, it has been shown that perturbation profiles calculated in the pr

The study of plasma turbulence and transport is a complex problem of critical importance for fusion-relevant plasmas. To this day, the fluid treatment of plasma dynamics is the best approach to realistic physics at the high resolution required for ce
