4 Conclusion
In this study, permeation cells are designed and fabricated which allow the determination of fluid properties such as pressure, temperature, and mass flowrate axially as
well as radially. In order to measure the radial mass flowrate, two different methods
are tried. In the traditional method, the mass flow meter positions are changed four
times in order to determine the mass flowrate from all the cells. In none of the test
case, mass flowrate recovery is 100% which is due to the variable back pressure.
This back pressure is caused by the use of the Coriolis mass flow meter that results in
change in fluid dynamics. While in the analytical method, all the cells are connected
to the mass flow meter that results in identical exit condition that does not change
the fluid dynamics inside the porous tube and results in 100% mass flow recovery.
