Theoretical Investigation of Creeping Viscoelastic Flow Transition Around a Rotating Curved Pipe
The study of creeping motion of viscoelastic fluid around a rotating rigid torus is investigated. The problem is solved within the frame of slow flow approximation. The equations of motion governing the first and second-order are formulated and solved for the first-order only in this paper. However, the solution of the second-order equations will be the subject of a part two of this series of p...
متن کاملMasters Thesis: Numerical Simulation of Core-Annular Flow in a Curved Pipe
A numerical study, using the volume-of-fluid method (VOF), has been made of core-annular flow in a curved pipe. We investigated two cases: core-annular flow in a 90◦ bend and in a 180◦ return bend. To verify our numerical method we first compared our results for a singlephase flow in a 90◦ bend with numerical results and experimental data given in the literature. The agreement was good. Thereaf...
متن کاملSteady Flow in a Curved Pipe with Circular Cross-Section. Comparison of Numerical and Experimental Results
Numerical solution has been obtained of the equations of motion of a viscous incompressible fluid in a curved annular conduit with circular cross-section. These equations are approximated by finite-difference equations which are of the second-order accuracy with respect to the grid sizes. The computed results are presented for the range 96 D 8000 , where D is the Dean number of the flow and for...
متن کاملA Numerical Study of the Effect of Aspect Ratio on Heat Transfer in an Annular Flow Through a 270-Degree Curved Pipe.
In the present paper, a three dimensional annular developing incompressible laminar flow through 270- degree curved pipe is numerically simulated. The dimensionless governing equations of continuity, momentums and energy are driven in toroidal coordinates. The governing equations are discretized by projection algorithm using forward difference in time and central difference in space. A three-di...
