In this investigation, attempts have been made to solve two-dimension nonlinear viscous flow between slowly expanding or contracting walls with weak permeability by utilizing a semi analytical Akbari Ganji's Method (AGM). As regard to previous papers, solving of nonlinear equations is difficult and the results are not accurate. This new approach is emerged after comparing the achieved solutions...

mhd boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. a system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order rung...

Various methods for calculating the capacitance of unloaded rolling elements are compared to improve electric characterization element bearings. Semi-analytical approximations and finite simulations applied a closed-form analytical two-dimensional solution is derived comparison. The results show that most common semi-analytical approximation, which uses effective radii express contact geometry,...
