	An Immersed Boundary Method for Flow Simulations Around Stationary and Moving Rigid Particles Havlica, Jaromír ; Trávníčková, Tereza ; Kohout, M. ; Růžička, Marek The main aim of this work was study of the particles motions and interactions by the evaluation of particles positions, velocities and accelerations. It was shown that immersed boundary method is able to successfully describe interactions between particle and fluid, the interactions between particle and particle and interactions between particle and wall. The results were quantitative compared with other studies. Fulltext: content.csg - PDF Plný tet: SKMBT_C22012102413450 - PDF Detailed record
	Experimentální výzkum Magnusovy síly působící na hladkou kouli při vysokých Reynoldsových číslech Kharlamov, Alexander ; Chára, Zdeněk ; Vlasák, Pavel The paper describes the results of experimental research dealing with rotating smooth spherical particles moving quasi-steadily in calm water. The motion of the particles was recorded by a digital video camera. The kinematics of the particles motion was analyzed numerically. The dimensionless Magnus force coefficient, the Reynolds number Re and spin parameter Γ (ratio of peripheral sphere velocity and translational velocity) were evaluated from the time series of the particle coordinates and its angle of rotation. The Magnus force was determined as a function of the Reynolds number and spin parameter for 3000 < Re < 42000 and 0.1 < Γ <7. The results were compared with results from literature and overall data were fitted by a simple function valid for 0.5 < Re < 140000 and 0.1 < Γ <10. Detailed record
	Shear-driven cavity flow at high Reynolds numbers Chára, Zdeněk ; Kysela, Bohuš ; Hoření, Bohumír The paper deals with a research of a shear-driven cavity flow at high Reynolds numbers (Re= 12000-100000). PIV method was used with a continuous light source and at selected profiles LDA method was used, too. Numerical k-omega, SST model was used for the same range of the Reynolds numbers.
