Steady 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 کاملEntropy Generation in Laminar Fluid Flow through a Circular Pipe
A numerical solution to the entropy generation in a circular pipe is made. Radial and axial variations are considered. Navier-Stokes equations in cylindrical coordinates are used to solve the velocity and temperature fields. Uniform wall heat flux is considered as the thermal boundary condition. The distribution of the entropy generation rate is investigated throughout the volume of the fluid a...
متن کاملThree-dimensional simulations of fluid flow around a curved tube with circular section
In order to decrease the fluid dynamic forces of the U-bent tube with a circular section and avoid the occurrence of fluid-structure interaction problems, three-dimensional simulations of fluid flows around the tubes are carried out. In the case that the axis of the curved tube with the circular section is prevented from being normal to the direction of the flows approaching the tube, the forma...
متن کاملPULSATILE MOTION OF BLOOD IN A CIRCULAR TUBE OF VARYING CROSS-SECTION WITH SLIP FLOW
Pulsatile motion of blood in a circular tube of varying cross-section has been developed by considering slip flow at the tube wall and the blood to be a non- Newtonian biviscous incompressible fluid. The tube wall is supposed to be permeable and the fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the tube wall. The tangential velocity of the fl...
متن کاملA Numerical Study on Non-Isothermal Flow Through a Rotating Curved Duct with Square Cross Section
Abstract: Non-isothermal flow through a rotating curved duct with square cross section is studied numerically by using the spectral method, and covering a wide range of the Taylor number, Tr, 2000 0 Tr and Dean number, , Dn 0Dn 2000. A temperature difference is applied across the vertical sidewalls for Grashof number Gr = 500, where the outer wall is heated and the inner one cooled. The r...
