On the Unsteady Plasma Flow Confined Between Two Rotating Cylinders

Our objective of this book is to mainly focus on the behavior of a plasma that is confined between two infinite coaxial circular rotating cylinders. The cylinders are rotating with angular velocity. The effects of Lorentz force on the electrons collected with each other, with positive ions, and with neutral atoms in the plasma fluid is studied. The BGK¿type of the Boltzmann kinetic equation is applied using a cylindrical coordinate system with Maxwellian velocity tow stream distribution functions. An exact analytical solution of the model equations for the unsteady flow was given using the moment and the perturbation methods. The manner of the mean velocity of plasmas is illustrated, which compatible with the variation of the shear stress, viscosity coefficient. Besides, a new thermodynamic prediction is investigated and applied for the whole system. Finally, qualitative agreements with previous related papers were demonstrated using 3-Dimensional graphics for the calculating variables. The significance of this book study is due to its vast applications in numerous fields such as in physics, engineering, commercial and industrial applications.
