MHD numerical analyses of hydrodynamically developing laminar liquid lithium duct flow

•Magnetohydrodynamic closed enclosure flow analyses were done.•Hydrodynamic flow parameters were investigated under vertically imposed magnetic field.•Increment of the magnetic field augmented the pressure of the fluid.•Flow velocity, viscosity and density of the fluid were minished by the appreciation of the magnetic field intensity.

Magnetic effects on steady state laminar liquid lithium duct flow were studied at hydrodynamically developing flow region. Studied duct model was constructed with dimensions are (15.7 × 5 × 150 mm). Model side walls were estimated conductive and top-bottom walls were defined insulated. Magnetic field applied with values are as B = 0 T, B = 0.05 T, B = 0.1 T and B = 0.15 T. Magnetic field effect was maximized by normally applying it on the flow stream. Hydrodynamic parameters are velocity, pressure, viscosity and density were numerically studied by ANSYS Fluent software MHD module. It is concluded that increase of magnetic field increased the local pressure but also decreased local velocity, density and dynamic viscosity. Obtained results compared with studies in literature and supported.
