    Computer Research and Modeling, 2014, v. 6, no. 2, pp. 285-294

    Problems of application of quasicellular networks for simulation of flows of visitors in different public spaces are considered. Quasicellular networks are basic discrete structures without signature. Proposed approach may be used to create simulations on micro and macro levels. It also may be used for creating geometrical models. There are also multi-flow systems for simulation of sports fans in a sports arena, propagation of fire and poison in public spaces. This approach satisfies the requirements of MOE of Russia № 7-3-113.

    The integrated model of eco-economic system on the example of the Republic of Armenia
    Computer Research and Modeling, 2014, v. 6, no. 4, pp. 621-631

    This article presents an integrated dynamic model of eco-economic system of the Republic of Armenia (RA). This model is constructed using system dynamics methods, which allow to consider the major feedback related to key characteristics of eco-economic system. Such model is a two-objective optimization problem where as target functions the level of air pollution and gross profit of national economy are considered. The air pollution is minimized due to modernization of stationary and mobile sources of pollution at simultaneous maximization of gross profit of national economy. At the same time considered eco-economic system is characterized by the presence of internal constraints that must be accounted at acceptance of strategic decisions. As a result, we proposed a systematic approach that allows forming sustainable solutions for the development of the production sector of RA while minimizing the impact on the environment. With the proposed approach, in particular, we can form a plan for optimal enterprise modernization and predict long-term dynamics of harmful emissions into the atmosphere.

    Effect of shape and sizes of a local heat source on convective heat transfer in a square cavity
    Computer Research and Modeling, 2015, v. 7, no. 2, pp. 271-280

    Numerical analysis of the effects of the local heat source shape on transient natural convection in a square enclosure has been carried out. The local heat source has rectangular, triangular and trapezoidal shape. The boundary value problem formulated in the dimensionless variables such as stream function, vorticity and temperature by using the Boussinesq approximation has been solved by means of finite difference method. Distributions of streamlines and isotherms and time dependences for the average Nusselt number along the heat source surface in a wide range of governing parameters have been obtained.

    The article provides a development of recently published turbulence model KEFV. The submitted version of this model allows modeling transition in a separated flow. The model includes an adjustable mechanism for specifying generation of turbulence in laminar zones with high velocity gradients. The model is implemented in the FlowVision CFD software.

    Modeling of H₂-permeability of alloys for gas separation membranes
    Computer Research and Modeling, 2016, v. 8, no. 1, pp. 121-135

    High-purity hydrogen is required for clean energy and a variety of chemical technology processes. A considerable part of hydrogen is to be obtained by methane conversion. Different alloys, which may be wellsuited for use in gas-separation plants, were investigated by measuring specific hydrogen permeability. One had to estimate the parameters of diffusion and sorption to numerically model the different scenarios and experimental conditions of the material usage (including extreme ones), and identify the limiting factors. This paper presents a nonlinear model of hydrogen permeability in accordance with the specifics of the experiment, the numerical method for solving the boundary-value problem, and the results of parametric identification for the alloy V₈₅Ni₁₅.

    Keywords: hydrogen interaction with solids, surface processes, boundary-value problems, numerical simulation.
