I would appreciate it if anyone can help me to get the values of the inertia resistance and viscous resistance for air flow through fiberglass on mineral wool used in thermal insulation.
Are you trying to simulate the flow through the fibreglass by assuming that as a porous media? If that is the case the inertial and viscous coefficients for porous media are found by fitting the Mass flow rate vs pressure drop curve for that fibre glass media by second order polynomial fit. The second order coefficient will give viscous coefficient and first order coefficient corresponds to the inertial coefficients of the porous medium.
Thanks Kalyana for the answer. Yes this is the case.Really I am asking if anyone has done the experiment and can share the values.
See paper by Pavel and Mohamad. My former student Pavel determined the coefficients experimentally and reported in his papers.
Many thanks for all the answers.However my question is is about the air flow through fiberglass or mineral wool specifically. I think I should insert a panel of fiberglass in a duct and force the air to flow through the panel. Then I can measure the pressure drop across the panel and the velocity of the air penetrating it. Just to save some time I prefer to take it from any publication rather than repeating the experiment.
