... influence on the mass flow rate and velocity profile in nanochannels. The predicted mass flow rates for the nanochannels with identical hydraulic diameter decrease with the cross-sectional geometry in the sequence as ellipse > equilateral triangle > square > circle. However, the ranking of velocity...

... diffusivity LBM where multiple diffusion mechanisms namely molecular diffusion, Knudsen diffusion and transition diffusion are involved. The advective and diffusive mass flow rates at a series of water saturation states and pressure conditions in the reconstructed clay and OM structures are calculated...
