A Modification of the Fictitious Domain Method with Brinkman Penalization and a Boundary Condition for Pressure for the Nonlinear Navier–Stokes Model

This paper investigates a modification of the fictitious domain method based on extension through lower-order coefficients, with a prescribed pressure boundary condition, for the nonlinear unsteady Navier–Stokes equations governing the motion of an incompressible homogeneous fluid in a bounded three-dimensional domain....

Development of a numerical method for solving the inverse hydroacoustic problem of gas-lift oil production

The object of this study is the propagation of hydroacoustic disturbances in a gas-lift well, where the main state variables are pressure and volumetric flow rate. The problem solved is the development of a numerical method for hydroacoustic problems, in which unknown initial distributions or harmonic input parameters...

A Brinkman-Penalized Finite Element Method for the Boussinesq Equations with Immersed Rigid Obstacles Under Uncertain Obstacle Motion

The Boussinesq equations are widely used to model incompressible thermally driven flows, but their numerical simulation becomes more challenging in domains containing fixed or moving rigid obstacles, particularly when the prescribed obstacle motion is uncertain. In this work, we develop a Brinkman-type fictitious-domai...

Radioactivity as a prospecting indicator of rare earth, gold and polymetal deposits in eastern Kazakhstan and an indicator of increased radioecological hazard during their development

This study evaluates the role of natural radioactivity as an exploration indicator for rare-metal, gold, and polymetallic mineralization in Eastern Kazakhstan, as well as its significance as a factor of radioecological hazard. The analysis is based on the results of regional radiohydrolithochemical surveys conducted at...
