   This literature is a research thesis concerning fundamentals of bulk solids and powdered materials pneumatic conveyors, flow design. At beginning gas-solid (particle) flow regimes in horizontal and vertical pipes are discussed. Then governing mathematical equations in two-phase flow of fluid-solid suspension with emphasis on  dilute gas-solid suspension are derived. Consequently on basis of recent equations and exercising an applied approach, flow equations of gas-solid suspension in pipe flow for the most general settlement state of a pipe, is obtained (This can be used for simulating blood flow in living beings). Applying these results and using practical parameters will offer governing equations of pneumatic conveying flow. Additionally, functional range of trajectory (Lagrangian) and two-fluid (Eulerian) analytical method is studied. Finally by introducing conservative variables numerical method and employing “point” model of governing equations, Lagrangian computerized simulation for dilute-phase semi-one dimensional pipe flow with variable cross sectional area is presented.
