摘要:Abstract(#br)In this paper the characteristics of the primary breakup of a liquid jet is analyzed numerically. We applied the Volumes of Fluids (VOF) approach utilizing the Direction Averaged Curvature (DAC) model, to estimate the interface curvature, and the Direction Averaged N...

摘要:Abstract(#br)This paper considers the effects of intermittent injection of a liquid jet or spray on the initial break-up and mixing of one fluid with the surrounding ambient fluid. The aim of the analysis is to describe the physical process and indicate the mechanisms that contro...

摘要:Abstract(#br)Large Eddy Simulation (LES) studies of isothermal and incompressible turbulent swirling flows in a model gas turbine combustion chamber geometry have been carried out. The focus is on the effect of outlet geometry contraction on the vortex breakdown structure and the...

摘要:Abstract(#br)Butler groups are torsion-free abelian groups which — in the infinite rank case — can be defined in two different ways. One definition requires that all the balanced extensions of torsion groups by them are splitting, while the other stipulates that they admit c...

摘要:Abstract(#br)The concept of roles has been prevalent in the area of Information Security for more than 15 years already. It promises simplified and flexible user management, reduced administrative costs, improved security, as well as the integration of employees’ business fu...

摘要:Abstract(#br)The wake flow behind a cantilever beam of quadratic cross-section at a Reynolds number of 50,000 is investigated using detailed simulations. Two cases are considered, the first one using a stiff beam and the second one with a beam allowing for elastic deformation due...

摘要:Abstract(#br)A new Scale-Selective Discretization (SSD) procedure for the Navier–Stokes equations is proposed. The aim is to reduce the numerical dissipation of already existing numerical schemes to make the SSD scheme easily implementable to the existing CFD codes. In parti...

摘要:Abstract(#br)The near-field characteristics of a turbulent jet with moderate swirl generated by a fully developed, axially rotating pipe flow are investigated with LDV, time-resolved stereoscopic PIV measurements, as well as with large-eddy simulations. Large-scale vortical ...

摘要:Abstract(#br)Simulations of aerated stirred reactor is performed using a combination of large eddy simulation (LES) and Lagrangian particle tracking (LPT). A single impeller Rushton turbine is positioned at the center of the reactor and air is introduced at the bottom through a c...
