Forced Convection Heat Transfer from a Circular Cylinder Embedded in Porous Media

چکیده
In this study an experimental work was performed to examine the effect of porous media on the heat transfer from a cylindrical heater in the case of steady-state forced convection. Porous media consisted of Spherical glasses of diameter 0.6 cm and air was used as the cooling fluid. The bulk temperature was approximated by the inlet temperature and Properties of the air were found at the film temperature. Mean Nusselt number of a cylinder is found both for clear fluid and porous media and the results were illustrated in dimensionless form. It was clearly pointed out that porous media enhanced the heat transfer rate compared to the clear fluid.

Conjugate Heat Transfer of MHD non-Darcy Mixed Convection Flow of a Nanofluid over a Vertical Slender Hollow Cylinder Embedded in Porous Media
In this paper, conjugate heat transfer of magneto hydrodynamic mixed convection of nanofluid about a vertical slender hollow cylinder embedded in a porous medium with high porosity have been numerically studied. The Forchheimer’s modification of Darcy’s law was used in representing the nanofluid motion inside the porous media. The governing boundary layer equations were transformed to non-dimen...
متن کاملThermal Field Around a Circular Cylinder with Periodic Vortex Shedding
A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...

A numerical investigation has been carried out for mixed convection flow in a rectangularventilated cavity with a heat conducting solid circular cylinder at the center. Forced convection flowconditions were imposed by providing an inlet at the bottom of the left wall and an outlet vent at the topto the other sidewall. In this paper, the effect of cavity aspect ratio as well as the mixed convect...
