Our results show that gas production in the Triple-Porosity Model with shape factor upscaled from DFN exhibits different production performance from models with uniform shape factor distribution.
The modelling of the material is carried out by adopting the constitutive law proposed by Eurocode 9, based on the Ramberg-Osgood model whose shape factor characterises the hardening behaviour of the material.
Each single profile from the satellite height to the ionosphere peak has been fitted by a semi-Epstein layer function of the type used in the DGR model with shape factor variable with altitude.
In the GGD models the shape factor,, can be estimated with four different methods [10].
The approximate analytical model for the shape factor presented in this paper is verified using fine-grid, finite element numerical simulation.
Applicability of the classic double-porosity model with a constant shape factor to low-permeability reservoir simulation is questionable (Cai et al. 2015).
An important characteristic of this model is the same shape factor as that in Lim and Aziz (1995) for Warren and Root's model.
Control G. RIC model Parameter vector Variance of, Shape factor of, Nonlinear RC model Parameter vector Variance of, Shape factor of, Cramer-Rao Lower Bound (CRLB) [11] is defined as (18).
On the other hand, the Patient group respiratory signals are fitted to the nonlinear RC model with lower measurement noise variance, better converged measurement noise shape factor, and model parameter tracks.
The inputs for the regression models are the building shape factor, the building envelope U-value, the window to floor area ratio, the building time constant and the climate which is defined as function of the sol-air temperature and heating set-point.
