Numerical Study of Heat Transfer in a Porous Pipe Subjected to Reciprocating Flow
Краткое описание
A numerical investigation has been carried out for laminar incompressible reciprocating flow and heat transfer in a pipe filled with a porous medium and with a finite length. The pipe walls are assumed at constant temperature. A general model for the momentum equation was employed. The model for the energy transport was based on the local thermal equilibrium assumption between the fluid and the solid phases. The control-volume-based finite element method is used for solving the differential system equations with an unequal order velocity-pressure interpolation. A comprehensive analysis of the influence of the Darcy number, the kinetic Reynolds number, the thermal conductivity ratio, the heat capacity ratio, and the dimensionless oscillation amplitude Ao is presented.
