Heat flux in the presence of shifting cold and hot electron Maxwellian distributions
Abstract
Heat flux is evaluated in the case of shifted Maxwellian velocity distribution function with cold and hot electrons. The heat flux associated with the cold electron temperature gradient nabla sub x T sub C tends to flow in the direction of increasing T sub C. This flux inversion is enhanced due to the shifting velocities of the cold and hot electrons. Even for a small shifting velocity as mv(2) sub H/2T sub H = 0.3 (v sub H and T sub H are the shifting velocity and the temperature of the hot electrons), value of the heat flux becomes more than twice as large as the value without the shifting velocities.
