    Unsteady free convection boundary layer flow over a heated plate with different inclinations
    (Department of Mathematics, BUET, 2008-12) Asma Begum; Abdul Maleque, Dr. Md.
    Unsteady free convection boundary layer flow over a heated plate with different inclinations have been studied numerically. The governing equations are then made dimension1css by_using usual similarity transformations. The dimensionless equations are solved numerically by appl}ing Nachtsheim-Swigert shooting iteration technique along with Runge-Kulla sixth order integration method. Two cases of the motion of the flow have been considered; one is the impulsive motion and the other is the unifonnly acce1crated motion _The plate temperature is assumed (0 be a function of time. The dimensionless ~elocity, temperature and pressure profiles aTe shown graphically for different values of the parameters entering into the problem - The numerical values of the local skin-friction and local Nussell number are also presented in tabular fOnTI. Finite difference analysis of natural convection flow over an inclined heated plate have been studied numerically. We have studied the natural convection flow over an inclined flat plate by employing implicit finite-difference method of Crank-Nicolson method. The transient ,-elocity and temperature prollles are displayed graphically and discussed thereafter. The stability and convergence of the implicit finite-difference scheme are established as well. The software fORTRAN 90 is used to perform computational job and the post processing software MS Excel has been used to display the numerical results graphically.
