【Abstract】 Laminar boundary layer flow of four constants Maxwell oldroyd fluid is investigated. The velocity distribution in boundary layer, the thickness of the boundary layer are shown. The relation between friction factor, Reynolds number, the material functions of Non newtonian fluids is given. For the laminar flow of Non newtonian fluids some drag reduction, like turbulent flow, has been found.更多还原
