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.
