Item Diffusion-thermo and thermal-diffusion effects on Rivlin-Ericksen rotatory convective flow past a porous vertical plate(Frontiers in Heat and Mass Transfer, 2018) Dada, M.S.; Agunbiade, S.A.; Titiloye, E.O.Diffusion-thermo and thermal-diffusion effects on unsteady, incompressible Rivlin-Ericksen rotatory convective flow of a magnetic conducting electrical fluid with time dependent suction between two vertical plates of which one is permeable are investigated. The uniform angular velocity rotates about an axis normal to the plate. The equations governing the flow model are non-dimensionalised, perturbed for simplification and solved by Adomian decomposition method. Graphical illustrations of the fluid parameters on velocity, temperature, concentration are presented and discussed. The effect of skin-friction, Nusselt and Sherwood numbers are presented in tabular forms and it is discovered from the results that a rise in thermal-diffusion parameter speedup the skin-friction, while increasing diffusion-thermo parameter slowdown the skin-friction.Item The effect of viscous damping on the dynamic behaviour of rectangular plates resting on elastic foundation under moving loads(Journal of Institute of Mathematics & Computer Sciences, Institute of Mathematics and Computer Sciences, India., 2008) Idowu, A.s.; Titiloye, E.O.; Dada, M.S.; Gbadeyan, J.A.The effect of viscous damping on the dynamic behavior of a plate under a moving line load is studied. The problem is formulated within the framework of the classical small deflection theory of thin plates. The solution to the problem are obtained by transforming the partial differential equation for the problem to coupled ordinary differential equations which were analyzed and evaluated for simply supported boundary conditions. It is shown that the deflection profile of the plate depends on the magnitude of the damping coefficient.Item Heat and mass transfer of oscillatory visco-elastic radiating hydromagnetic flow through a vertical channel with hall effects(Confluence Journal of Pure and Applied Sciences, Federal University Lokoja, Nigeria., 2017) Titiloye, E.O.; Dada, M.S.; Adeosun, A.T.Heat and mass transfer of oscillatory hydrodynamics convective Visco-elastic incompressible fluid flow in a vertical channel with Hall effects is investigated. The equations governing the problem are simplified, non-dimensionalized and solved using Differential Transform Method. The results compared well with existing literature. The effects of the salient fluid parameters are discussed and presented in tabular and graphical forms.Item On the response of plate on winkler foundation to a moving distributed line load(ABACUS, Mathematical Association of Nigeria., 2004) Dada, M.S.; Idowu, A.S.; Titiloye, E.O.The dynamics response of a plate on winkler foundation subjected to a moving distributed line load is presented. The assumption of variable separation mode shapes method transforms the partial differential equation governing the motion of the plate, which in general is a function of x,y and t, into a function of one independent variable, The resulting equation is analyzed by a finite difference method. The results for simply supported boundary conditions are used as illustrative example. It is found that distributed moving mass problem produces the upper bound deflection, when compared with a concentrated moving mass problem.Item Unsteady free convection of magneto-hydrodynamic radiative flow past an infinite vertical porous plate in a porous medium(ICASTOR Journal of Mathematical Sciences, 2012) Dada, M.S.; Titiloye, E.O.; Oyekunle, T.L.The unsteady free convection of magneto- hydrodynamics radiative fluid flow past an infinite vertical porous plate in a porous medium under the limit of an optically thin fluid is investigated. An implicit finite difference scheme of crank- Nicolson type was employed in solving the resulting coupled non-linear partial differential equations to obtain the dimensionless velocity and temperature. Velocity and temperature fields have been studied and their profile are graphically presented while velocity gradient and Nusselt number are shown in a tabular form. It is observed, among others that the radiation parameters decreases the velocity and temperature of the field while the suction/ injection parameters lead to an increase in transient velocity and temperature of fluid. Also, a rise in the magnetic field and permeability parameters reduces the velocity significantly and temperature slightly.
