Coarse-graining of CFD-DEM for simulation of sand production in the modified cohesive contact model
Daniyar Kazidenov, Furkhat Khamitov, Yerlan Amanbek
Sand production is an important issue for many hydrocarbon recovery applications in unconsolidated reservoirs. The model using the Computational Fluid Dynamics coupled with Discret…
Inverse properties of a class of pentadiagonal matrices related to higher order difference operators
Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek
This paper analyzes the convergence of fixed-point iterations of the form u = f(u) and the properties of the inverse of the related pentadiagonal matrices, associated with the four…
Inverse properties of a class of seven-diagonal (near) Toeplitz matrices
Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek
This paper discusses the explicit inverse of a class of seven-diagonal (near) Toeplitz matrices, which arises in the numerical solutions of nonlinear fourth-order differential equa…
A proof of Anđelić-Fonseca conjectures on the determinant of some Toeplitz matrices and their generalization
Bakytzhan Kurmanbek, Yerlan Amanbek, Yogi Erlangga
We present a proof of determinant of special nonsymmetric Toeplitz matrices conjectured by Anđelić and Fonseca in \cite{andjelic2020some}. A proof is also demonstrated for a more g…
Framework of Fracture Network Modeling using Conditioned Data with Sequential Gaussian Simulation
Yerlan Amanbek, Timur Merembayev, Sanjay Srinivasan
The fracture characterization using a geostatistical tool with conditioning data is a computationally efficient tool for subsurface flow and transport applications. The main object…
Error indicator for the incompressible Darcy flow problems using Enhanced Velocity Mixed Finite Element Method
Yerlan Amanbek, Gurpreet Singh, Gergina Pencheva +1
In the flow and transport numerical simulation, mesh adaptivity strategy is important in reducing the usage of CPU time and memory. The refinement based on the pressure error estim…
