Journal of KONES
2019 Vol. 26, No. 1 175--181
EN In trimmed flight of a helicopter, all the forces and moments, aerodynamic, inertial, and gravitational, are in balance. Keeping the helicopter in trimmed state, needs a precise adjustment of flight controls. The methodology of simulation of a fully trimmed flight of rotorcraft has been developed an[...]

PL Przedstawiono wyniki modelowania przepływu burzliwego dwufazowego typu ciecz-ciecz w mieszalniku statycznym z dziesięcioma wkładkami Kenics. W badaniach numerycznych wykorzystano technikę RANS i URANS dla liczby Reynoldsa, Re równej 10 000. W modelowaniu CFD przepływu dwóch płynów newtonowskich zast[...]
EN Results of turbulent, two-phase flow simulations in a static Kenics mixer formed by ten inserts are presented. The computational fluid dynamics study was carried out using both the RANS and URANS approaches. Reynolds number was 10 000. The simulation results obtained for the RANS and URANS methods w[...]

PL Zaprezentowano badania numeryczne przepływu burzliwego dwufazowego w mieszalniku statycznym Kenics. W badaniach CFD wykorzystano dwa podejścia: symulacji wielkowirowych LES z modelem dynamicznym kinetycznej energii burzliwości skali podsiatkowej (Dynamie Kinetic Energy Subgrid-Scale Model) oraz meto[...]
EN Results of numerical modelling of two-phase turbulent flow in a Kenics static mixer were presented. The CFD simulations were carried out using two approaches: 1) large eddy simulation with the dynamic kinetic energy subgrid-scale model, and 2) unsteady RANS method with the k-e model. Numerical simul[...]
