چکیده
The goal of this work is to employ a semi-analytical framework investigate key features associated with the transport behavior an inert solute in non-Gaussian random fields. We focus our analysis on dynamics plume through porous medium characterized by spatially heterogeneous log-conductivity fields, Y. rest stochastic Lagrangian provide formulations evaluate statistical moments and cumulative distribution function (CDF) concentration. structure field modeled as Generalized Sub-Gaussian process. This model has been shown capture scale-dependent displayed several variables, including parameters media. Our results suggest that effects non-Gaussianity Y concentration statistics are more pronounced at locations near source zone early times. impact analyzed nature also significant lower tails distribution. explore conditions under which when CDF fields can be approximated widely used beta Furthermore, methodology alternative commonly numerical Monte Carlo method employed benchmark tool computational mass problems

15 صفحه اولTransport Property Estimation of Non-Uniform Porous Media
In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...

متن کاملNon-Gaussian distribution in random advection dynamics.
Simulations of vortex tube dynamics reveal that the non-Gaussian nature of turbulent fluctuation originates in the effect of random advection. A similar non-Gaussian distribution is found numerically in a simplified statistical model of random advection. An analytical solution is obtained in the mean-field case.
