    A review on natural convection flow along a vertical flat plate
    (Eastern University, 2011-01) Ferdousi, Amena
    Natural convection flow along a vertical flat plate has been revisited with respect to thermal conductivity, magnetic parameter, heat conduction, joule heating, coupling conduction, conjugate heat transfer and heat generation and finally a comparative analysis of free convection flow along a vertical flat plate is presented in this work where analysis are broadly discussed in order to discover the results in all the case. The graphical presentation of the surface shear stress in terms of skin friction coefficient and the rate of heat transfer in terms of local Nusselt number, velocity as well as temperature profiles are shown graphically for a selection of parameters set, consisting of magnetohydrodynamic parameter M, heat generation parameter Q, thermal conductivity n, joule heating J, coupling conduction p, Prandtl number Pr.

    DISSIPATION EFFECT ON A FREE CONVECTION FLOW PAST A POROUS VERTICAL PLATE
    (Daffodil International University, 2011-01-01) Ferdousi, Amena; Alim, M. A.
    A Numerical study on the effect of dissipation on a steady free convection flow through a porous vertical plate is made. The relevant non-leaner boundary equations are made dimensionless using specific non-dimensional variables. The corresponding non-similar partial differential equations are solved using implicit finite difference method with Keller-Box scheme. The results are then presented graphically and discussed thereafter.

    Mathematical Catastrophe Revisited
    (Eastern Univeristy, 2009-01-01) Rahman, M. Mostafizur; Ferdousi, Amena; Parvez, M. Salek
    Different models of mathematical catastrophes of single variable have been Studied and finally from the substance we have found a mathematical analysis Of mathematical catastrophe. Two mathematical catastrophes viz, fold catastrophe and cusp catastrophe are broadly discussed in order to find some results newly in both the cases.

    NATURAL CONVECTION FLOW FROM A POROUS VERTICAL PLATE IN PRESENCE OF HEAT GENERATION
    (Daffodil International University, 2010-01-01) Ferdousi, Amena; Alim, M. A
    Natural convection flow from a porous vertical plate in presence of heat generation have been presented here. The governing boundary layer equations are first transformed into a non dimensional form and the resulting non linear system of partial differential equations are then solved numerically using finite difference method together with Keller-Box scheme. The numerical results of the surface shear stress in terms of skin friction coefficient and the rate of heat transfer in terms of local Nusselt number, velocity as well as temperature profiles are shown graphically and tabular form for a selection of parameters set of consisting of heat generation parameter Q, Prandtl number Pr.
