EXPERIMENTAL STUDY ON FLOW AND HEAT TRANSFER IN POROUS MEDIA
Abstract
The flow and heat transfer experiments for water in porous media were studied, and the experimental correlation
was given by changing the structural parameters of porous media solid skeleton. The experimental results show
that the pressure drop of the porous medium increases with the increase of Reynolds number in the porous
medium, and when the Reynolds number is large, the inertial force plays a major role. When the temperature of
the solution is increased, the pressure drop of the water decreases obviously. The frictional resistance coefficient
of the porous medium decreases with the increase of the Reynolds number, and the larger the porosity is, the
larger the frictional resistance coefficient is. When the fluid velocity is small, the resistance coefficient increases,
and the fluid velocity is large, the change of the frictional resistance coefficient is very slow. With the flow of
particles Reynolds number increases, the local Nusselt number is also increasing. The local Nusselt number
changes with the Reynolds number, when the Reynolds number is large, the smaller the porosity, the smaller and
the local Nusselt number.
