In this paper we study the large time behavior of solutions to the Navier-Stokes equations. We present a brief survey of results concerning energy decay, and discuss a related phenomenon of the large time energy concentration in the frequency space occurr... see more

The questions of transfer of radio-active sedimentov in reservoirs are examined. The basis for the design of diphasic flows is solution of the Navier-Stokes equations system and turbulent motion of liquid in the limited area of reservoir (rivers). For sol... see more

Neste trabalho, soluções numéricas das equações bidimensionais de Navier-Stokes e Euler utilizando o método MacCormack em malha estruturada multi-block é apresentado para regime permanente e não permanente de escoamentos de fluidos compressíveis. A técnic... see more

In this work, we applied different extrapolation techniques in association with the multigrid method to discover which one is the most effective in reducing the iteration error and the processing time (CPU time), as well as in improving the convergence fa... see more

Adstract. Statement of the  problem. The question of the qualitative and quantitative determination of the degree of negative influence of icing on the aircraft during the flight in adverse meteorological conditions, which has a specific layout, conf... see more

CFD simulation investigated turbulent flows in equal gas pipeline tees, in which the gas flow completely moves from the main line to the branch. The study was performed for tees of different geometry – stamped with different bending radii of the transitio... see more

Context. This article is devoted to the linear problem of the steady and unsteady flows of a viscous incompressible fluid.Objective. The purpose of this paper is to compare the previously developed methods of numerical analysis of the steady and unst... see more

The common approach for the flow factor calculation is based on using the Reynolds equation to simulate the micro-level flow. However, for structured surfaces the fluid flow cannot be represented correctly, due to the assumptions made when deriving the Re... see more

O escoamento laminar bidimensional de um fluido incompressível, governado pelas equações de Navier-Stokes, é o foco deste trabalho. Para tanto, utilizou-se o método de volumes finitos (MVF), com esquema de aproximação de segunda ordem (CDS), além de um mé... see more
