    Numerical simulation of heat and mass transfer processes in microchannels using CFD-package σFlow
    Computer Research and Modeling, 2012, v. 4, no. 4, pp. 781-792

    This article is dedicated to numerical modeling of heat and mass transfer processes in microchannels. Microchannels are channels, that characteristic diameter is about 100 μm. Interest to the study of processes in them is growing every year, due to the rapid development of microfluid technique. The study was conducted using the software package σFlow. Isothermal and nonisothermal flows in microchannels of various configurations were considered. The obtained results were compared with available experimental and analytical data. In general for all problems a good agreement was obtained.

    Keywords: microchannels, CFD, mircofluid technique, numerical modelling.

    Numerical modeling of flows with flow swirling
    Computer Research and Modeling, 2013, v. 5, no. 4, pp. 635-648

    This paper is devoted to investigation of the swirl flows. Such flows are widely used in various industrial processes. Swirl flows can be accompanied by time-dependent effects, for example, precession of the vortex core. In turn, the large-scale fluctuations due to the precession of the vortex can cause damage of structures and reduce of equipment reliability. Thus, for engineering calculations approaches that sufficiently well described such flows are required. This paper presents the technique of swirl flows calculation, tested for CFD packages Fluent and SigmaFlow. A numerical simulation of several swirl flow test problems was carried out. Obtained results are compared with each other and with the experimental data.
