Am. Mirza et al., Anomalous heat transport and vortex formation due to electron-temperature-gradient driven drift waves in a sheared flow plasma, PHYS SCR, 60(3), 1999, pp. 261-264
By employing Braginskii transport equations for electrons, we derive a syst
em of nonlinear equations which govern the dynamics of low-frequency short-
wavelength electromagnetic waves in the presence of equilibrium density, te
mperature and magnetic held gradients. New electron-temperature-gradient dr
iven electromagnetic drift-wave instabilities are shown to exist. Anomalous
electron energy transport caused by nonthermal electromagnetic fluctuation
s is also derived. Furthermore, possible stationary solutions of the nonlin
ear system are obtained in the form of spatially bounded dipolar as well as
chain of vortices. The results of our investigations should be helpful to
understand the wave phenomena in space and laboratory plasmas.
