This numerical study investigates the steady state natural convection of light and heavy water entering a vessel from the left and leaving on the right. The cavity consists of a matrix of cylindrical heated rods as in light and heavy water reactors. The aim of the study is to describe the effects of water inlet velocity on the flow and thermal fields in presence of such heated obstacle. The inv...

În prezenta lucrare a fost realizat un studiu asupra evoluţiei presiunii în timpul exploziei sub formă de deflagraţie produse în amestecuri propan-aer aflate într-o celulă cilindrică (Φ = 10 cm; h = 15 cm) cu aprindere centrală, la diferite concentraţii iniţiale de propan (între 2.60 şi 5.70%, in vol.), la diferite presiuni iniţiale (între 0.3 şi 1.3 bar) şi la temperatura iniţială ambiantă. Su...

A model is a simplified representation of an object. The modeling stage could be described as shaping individual objects that are later used in the scene. For many years scientists are trying to create an appropriate model of the blood vessels. It looks quite intuitive to believe that a blood vessel can be modeled as a tubular object, and this is true, but the problems appear when you want to c...

Shockwave lithotripsy repeatedly focuses shockwaves on kidney stones to induce their fracture, partially through cavitation erosion. A typical side effect of the procedure is hemorrhage, which is potentially the result of the growth and collapse of bubbles inside blood vessels. To identify the mechanisms by which shock-induced collapse could lead to the onset of injury, we study an idealized pr...

We present results on the synchronization of helicity in a liquid-metal Rayleigh–Bénard experiment under influence tide-like electromagnetic forcing with azimuthal wavenumber m = 2. show that for critical strength typical large-scale circulation cylindrical vessel aspect ratio unity is entrained by period forcing, leading to synchronized oscillations opposite signs two half-spaces. The obtained...
