Riga Plate

Purpose The purpose of this paper is to explore the flow of Cu-water and Ag-water nanofluids past a vertical Riga plate. The plate is infinite in height and has zero normal wall flux through its surface. Influence of thermal radiation, slip, suction and chemical reaction on the flow characteristics are reported. Design/methodology/approach Non-dimensional forms of the flow governing equations are obtained by means of a set of similarity transformations. Numerical solution is obtained with the help of fourth-fifth-order Runge–Kutta–Fehlberg method with shooting procedure. Comparison of solution profiles of Cu-water and Ag-water nanofluids are presented graphically and with the help of tables. Influence of pertinent parameters on skin friction and heat transfer rate is also reported. Findings Results reveal that the skin friction coefficient is more prominent in the case of Ag-water nanofluid for an increase in thermal radiation and volume fraction. The role of suction and slip is to increase velocity but decrease the temperature in both nanofluids. Temperature and velocity of both nanofluids increase as volume fraction and thermal radiation values are augmented. Heat transport increases with thermal radiation. Region near the plate experiences rise in nanoparticle concentration with an increase in chemical reaction parameter. Originality/value A complete investigation of the modeled problem is addressed and the results of this paper are original.

A numerical study is developed to examine the behavior of the forced/free convective flow towards a stretchable Riga plate with generalized Fourier’s law. The flow is saturated through Darcy–Forchheimer porous space and generated due to linear and second-order velocity slip phenomena. Here, the main consideration is given to the energy equation which is modeled in the presence of generalized Fourier’s law and heat generation absorption. Stagnation point is also discussed. Appropriate similarity variables lead to ordinary differential equations. The dimensionless coupled equations i.e., momentum and energy are numerically solved by the Built-in-Shooting method. The obtained results divulge that the velocity field declines versus rising values of Darcy–Forchheimer number. The temperature field of the working fluid boosts versus higher estimation of Eckert number and heat generation/absorption parameter. The important factors i.e., skin friction coefficient and temperature gradient of this research work are calculated by graphically subject to mixed convection parameter, modified Hartmann number, Prandtl number and heat generation parameter. It is observed from the graphical results that the impact of skin friction is more between the stretched Riga surface and fluid particles in the presence of rising values of mixed convection parameter.
