Analytical Solutions of Fluid Flows Through Composite Channels
Краткое описание
Fluid flow is assumed to be steady, incompressible, with a negligible gravitational force, and is constrained in an infinite horizontal channel composed of one or more different types of porous media. The cross section of the channel is taken to be both rectangular and circular. The nondimensional Brinkman equation involves the parameter α=Γ/Da, where Da is the Darcy number which represents the type of medium in which the fluid flows and Γ is the ratio of the fluid viscosity μf to the effective viscosity μ In this article an analytical study in the fully developed section of the three-dimensional composite channel is presented for different geometrical configurations, namely, when the channel consists of (1) a single porous medium of uniform porosity; (2) two different uniform porous media; (3) three porous layers each of uniform porosity, including when assembled to produce a symmetrical situation; and finally, (4) an axisymmetric channel with two different cylindrical porous regions of uniform porosity. The analytical solutions for different cases are compared and the effect of the Darcy parameter is discussed.
