In the present book, we study new unsteady effectiveness of a centrifugal force and heat transfer on a gas. We solve a system of non-linear time-dependent partial differential equations using exact analytical and numerical techniques. Our model is examined to follow the manner of the macroscopic properties of a gas bounded between two parallel horizontal rigid fixed plane plates. The moment and travelling wave methods are utilized. Comparison between the perturbed distribution function and the equilibrium one with time is investigated. System internal energy change is investigated. We...
