Unsteady hydromagnetic flow and heat transfer on a continuously moving vertical surface with thermal radiation

摘要

An analytical solution foi an unsteady hydromagnetic convection flow over a continuously vertical surface with time-varying suction is discussed The system is stressed by uniform magnetic field with thermal radiation. A flow of this type represents a new class of boundary-layer flows at a surface of finite length. The solutions of the velocity and temperature distributions are obtained These solutions are discussed numerically, the effects of the various parameters such that the radiation parameter, the magnetic-field parameter, the Groshof and the Prandtl numbers are studied and shown graphically- The effects of the above parameters on the skin friction are computed and tabulated.
