Designed for regular grids, the LB approach meets the boundary conditions accurately with an unified "multi-reflexion" technique, introduced to fit pressure head and/or specified flux conditions on static and seepage boundaries.
It is also shown that determining Ergun coefficients by curve fitting pressure as a function of time and distance is a more satisfactory way of proceeding thant utilizing coefficients measured from steady-state experiments.
For calculating air core diameter a polynomial equation is fitted between pressure difference and the pressure transmitter reading.
Its outer casing is made of silicone and is fitted with pressure sensors so that it knows what it is touching.
We estimated the balloon elastance based on the fitted balloon pressure and volume data, and our results (0.1 to 0.4 cmH2O/ml, Fig. 3d) were comparable to those reported by Cross et al. [16].
Postulating the mixture is thermodynamically ideal, best fit pressure correlations are determined which result in less than 5% error between theory and experiment.
By comparing droplet evaporation data to discretized theoretical continuum mass flux rates which employ two parameter exponential vapor pressure/molecular weight correlations, best fit pressure correlation parameters are determined.
Since correlations for critical pressure are in general less accurate than correlations for critical temperature, the critical pressure of the C20+ fraction together with the binary interaction parameter C20+/CO2 was used as regression variables to fit experimental pressure saturation data with the modified Peng Robinson EOS.
Mean aerodynamic forces measured by a classical dynamometer balance fit the pressure measurements.
While this equation can fit vapor pressure data over the entire temperature range including the vicinity of the critical point, indiscriminate use of this equation can lead to substantial extrapolation errors and erroneous enthalpies of vaporization.
After that, to evaluate the effect of the channel end fitting on pressure drop, 36 single-phase cases and 54 two-phase flow cases under various flow conditions, which might occur during shutdown, were conducted, respectively.
