Title report: Actual Problems of Hydrodynamics and Conjugated Heat- and Masstransfer in Internal Systems with Any Configuration of Surface?
Reporter: Sergey N. Kharlamov, Professor at Tomsk State and Polytechnic Universities, Tomsk, Russia
Abstract:
The report is devoted discussion of actual problems of complex mathematical modelling and numerical simulation of inhomogeneous anisotropic turbulence, heat- and masstransfer in technical devices with any wall configuration for needs of power system, mechanical engineering, space-rocket techniques, oil and gas industry. These devices work at high thermal loadings and are accompanied of laminarization, swirling and the transitive laminar and turbulent effects. Structure of complex shear flows is studied in detail by RANS-FLUXES model with original basic base from the transport equations for scales of dissipative dynamic and thermal times. Scientific and technical information about distributions of temperature, velocities and their correlations in basic schemes of realisation of the swirled flows is presented. Explanation of the mechanisms accompanying function of these devices is given. These data have great importance at testing and calibration of codes for modelling and prediction of complex shear flows and conjugated heat- and mass transfer in technical applications.
