EXACT SOLUTIONS FOR FLOW OF A SISKO FLUID IN PIPE
By means of He's homotopy perturbation method (HPM) an approximate solution of velocity eld is derived for the ow in straight pipes of non-Newtonian uid obeying the Sisko model. The nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to He. Furthermore, the obtained solutions for velocity eld is graphically sketched...
متن کاملFlow of Gases through Tubes and Orifices
The nature of gas flow in pipes and ducts changes with the gas pressure and its description is generally divided into three parts or regimes. The flow dynamics are characterized by A, the molecular mean free path, in relation to some characteristic dimension such as the diameter of a pipe. The flow regime cannot be determined from the mean free path alone but only from the relation of this para...

15 صفحه اولOn the Performance of Different Empirical Loss Equations for Flow Through Coarse Porous Media (RESEARCH NOTE)
In this paper, the empirical equations that estimate hydraulic parameters for non-linear flow through coarse porous media are evaluated using a series of independent data collected in the laboratory. In this regard, three different relatively uniform soils ranging in size from 8.5 to 27.6 mm have been selected and three random samples drawn from each material. The physical characteristics such ...
