Webb8 apr. 2024 · The reservoir porosity \(\phi _r\) is constant and equal to 0.2 and permeability \(k_r\) is also constant and equal to 10 mDarcy. We can see the methane concentration profile in Fig. 7 . Compared to the equivalent result by Hoteit and Firoozabadi ( 2005 ), we understand that the result for the refined mesh has little numerical diffusion and agrees … Webb13 apr. 2024 · For various porosity values of a Rivlin-Ericksen elastico-viscous nanofluid, Fig. 2a displays the difference between the (Ra) with wave number a. The stationary Rayleigh’s number (Ra) increase as a porous medium’s porosity rises, demonstrating the porosity has stabilising effect on the system. cornwall sketches
