... the graded panel's effective properties. Also, even (PRT-I) and uneven (PRT-II) distributions of porosity are considered in the present work. The temperature-dependent (TD) properties are adopted in association with variable temperature fields, i.e., uniform (TD-I), linear (TD-II), and nonlinear (TD-III...

... gaskets based on measurements of gas flow at different pressures. In fact, an extrapolation of the porosity parameter approach ( Grine, L., and Bouzid, A., 2009, “Correlation of Gaseous Mass Leak Rates Through Micro and Nano-Porous Gaskets,” ASME Paper No. PVP2009-77205 ) used to correlate leak rates...

... on the calculation of the gasket porosity parameters ( D and N ) using a model based on a first order slip flow regime. The model assumes the flow to be continuum but employs a slip boundary condition on the leak path wall. Experimental measured gas flow rates were performed on gaskets with a microscopic flow rate...
