Aligned MHD free convection flow of magnetic nanofluid over a moving vertical plate with convective boundary condition / Siti Nur Hidayatul Ashikin Ibrahim

The present study investigates the behaviour of aligned magnetohydrodynamic (MHD)free convection flow of magnetic nanofluids over a moving vertical plate by considers two types of the mixtures of magnetic nanofluids which were water and kerosene based magnetic nanofluids. The convective boundary con...

Runge-Kutta formulas Magnetic fields The present study investigates the behaviour of aligned magnetohydrodynamic (MHD)free convection flow of magnetic nanofluids over a moving vertical plate by considers two types of the mixtures of magnetic nanofluids which were water and kerosene based magnetic nanofluids.
