Calculation of the steady flow through a curved tube using a new finite-difference method
A numerical method is described which is suitable for solving the equations governing the steady motion of a viscous fluid through a slightly curved tube of circular crosssection but which is also applicable to the solution of any problem governed by the steady two-dimensional Navier-Stokes equations in the plane polar co-ordinate system. The governing equations are approximated by a scheme whi...
متن کاملUpstream propagating curved shock in a steady transonic flow∗
We derive a new set of equations to give successive positions of slowly moving and slowly turning curved shock front in a transonic flow. The equations are in conservation form two of these are kinematical conservation laws. keywords Curved shock propagation, shock dynamics, ray theory, transonic flow.
متن کاملFlow Visualization Around a Non - Circular Tube
The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...
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 کاملAnalytical Study of A Two-Phase Model For Steady Flow of Blood in A Circular Tube
The present paper deals with a mathematical model of blood flow through narrow circular tube. The model consists of a core region of suspension of all the erythrocytes assumed to be a power law fluid and a peripheral cell-depleted layer of plasma as a Newtonian fluid. The system of differential equations has been solved analytically. The expressions for velocity profile, Bluntness parameter, fl...
