(a) The inlet Mach number prediction of different gases with different HCR (γ) for achieving nanoscale Sanal flow choking condition for diabatic flows. (b) The solution curve of Eq. (2a) is showing the 3D blockage factor with Methane as the working fluid. (c) The solution curve of Eq. (2b) is showing the 3D blockage factor in the sonic-fluid-throat of a nano scale fluid flow system with hydrogen as the working fluid. (d) The demonstration of the Sanal flow choking in diabatic nanoscale fluid flows. (Solution curves of Eq. 4). (e) Mach Number-Entropy chart of Fanno, Rayleigh and Sanal flow models at the choked flow condition (f) Analytical predictions of the average friction coefficient at the Sanal flow choking condition of different nanotubes at different inlet conditions.
