A comprehensive study of a copper-water nanofluid flowing through a porous medium embedded in an inclined channel is presented in the current article. The permeability of the porous medium is assumed to vary exponentially across the width of the channel. Navier slip at the channel walls is taken into account while the walls are also convectively heated, albeit asymmetrically. The lower wall of the channel is assumed to be made of a Riga plate, a new type of electromagnetic plate made of electrodes and magnets, inducing a plate parallel Lorentz force. Appropriate transformations are applied to the governing equations such that they are non-dimensionalised. The obtained equations are then solved using the homotopy analysis method. For a reduced form of the governing equations, analytical solutions are obtained which are similar to previously presented results. Graphical presentations are discussed for various flow parameters. The impact of the classical Hartman number on the flow is seen to be very significant and can play a pivotal role in reduction of entropy and skin friction. The flow scheme presented in the present article is presented for the first time in literature.

The impact of taper ratio, dihedral angle and wing tip shape on the aerodynamics of a very light aircraft's wing has been investigated by performing URANS simulations at Reynolds number of 5 × 106 for pre- and post-stall conditions. SD 7062 airfoil is selected for the cross-section of the wing geometries investigated. The mean aerodynamic coefficients are found to be invariant to these wing design parameters investigated at low angles of attack. On the other hand, reducing the taper ratio from 1 to 0.5 yields an in-crease in the stall angle of attack and the maximum lift coefficient. The increase of the dihedral angle from 0° to 5° does not lead to any change in the stall angle, however it results a slightly higher maximum lift coefficient with smoother stall behaviour. As evident in the mean surface streamlines, the stall cell formation is observed just above the stall angle for all three wing geometries investigated. The stall cell characteristics with respect to different finite wing design variables and angles of attack are represented and their effects on the sectional lift distributions and total aerodynamic coefficients are discussed.
