15 صفحه اولinvestigation of turbulent kinetic energy redistribution in a channel flow using direct numerical simulation
in this study, the turbulent kinetic energy redistribution process is investigated. to this aim, the direct numerical simulation (dns) of incompressible flow of a newtonian fluid through a channel at a shear reynolds number of reτ = 180 is used to produce a flow data base. then, these data are statistically analyzed. the turbulent kinetic energy redistribution is studied using the pressure-stra...
متن کاملDerivation of turbulent energy in a rotating system
Energy equation for turbulent flow in a rotating system was derived in terms of second order correlation tensors, where the correlation tensors were functions of space coordinates, distance between two points and time. To reveal the relationship of turbulent energy between two points, one point was taken as origin of the coordinate system. Due to rotation, the Coriolis force played an important...
متن کاملStepped Spillway Performance: Study of the Pressure and Turbulent Kinetic Energy versus Discharge and Slope
In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...
متن کاملTurbulent kinetic energy in normal and myopathic left ventricles.
PURPOSE To assess turbulent kinetic energy (TKE) within the left ventricle (LV) of healthy subjects using novel 4D flow magnetic resonance imaging (MRI) methods and to compare TKE values to those from a limited group of patients with a spectrum of dilated cardiomyopathy (DCM). MATERIALS AND METHODS 4D flow and morphological MRI data were acquired in 11 healthy subjects and 9 patients with dif...
