Verification of Baffle Factor for Straight Pipe Flow

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...

Numerical Simulation and Verification of Weight Function of Electromagnetic Flow Meter with Non-insulation Pipe Wall

Weight function distributions for an electromagnetic flow meter with a non-insulating pipe are numerically simulated and verified. The weight function distribution is very important for solution of flow velocity of distribution. In this paper, a finite element method (FEM) is used for solving the weight function distribution for this novel electromagnetic flow meter. First of all, a numerical s...

Stability analysis for two - phase pipe flow

Spectra and pseudospectra for pipe Poiseuille flow

Numerically computed spectra and pseudospectra are presented for the linear operator that governs the temporal evolution of infinitesimal perturbations of laminar flow in an infinite circular pipe at Reynolds numbers 1000, 3000 and 10 000. The spectra lie strictly inside the stable complex half-plane, but the pseudospectra protrude significantly into the unstable half-plane, reflecting the larg...
