Axioms, 2022 Separate flow friction formulations for laminar and turbulent regimes of flow through pipes are in common use in engineering practice. However, variation of different parameters in a system of conduits during conveying of fluids can cause changes in flow

The unsteady turbulent flows structure study present status [PDF]
INCAS Bulletin, 2019 The processes of heat transfer and hydraulic plays a very important role in the design and prototyping of aerospace technology. In most cases this technique works under significant unsteady conditions. Steady approach for unsteady processes leads to high

Resolved energy budget of superstructures in Rayleigh-B\'{e}nard convection [PDF]
, 2020 Turbulent superstructures, i.e. large-scale flow structures in turbulent flows, play a crucial role in many geo- and astrophysical settings. In turbulent Rayleigh-B\'{e}nard convection, for example, horizontally extended coherent large-scale convection ...

Laminarization of inhomogeneous turbulent channel flow under stable density stratification
Journal of Fluid Science and Technology, 2021 Effects of buoyancy force stabilizing the disturbances are investigated on a turbulent channel flow bounded by two walls of different temperatures. With a constant mean pressure gradient imposed, the buoyancy force related to the Grashof number (Gr) is ...

Modeling and simulation of inertial drop break-up in a turbulent pipe flow downstream of a restriction. [PDF]
, 2012 This work deals with the modeling of drop break-up in an inhomogeneous turbulent flow that develops downstream of a concentric restriction in a pipe. The proposed approach consists in coupling Euler–Lagrange simulations of the drop motion to an interface

Theory to predict shear stress on cells in turbulent blood flow.
PLoS ONE, 2014 Shear stress on blood cells and platelets transported in a turbulent flow dictates the fate and biological activity of these cells. We present a theoretical link between energy dissipation in turbulent flows to the shear stress that cells experience and ...

Magnetic Fields Produced by Phase Transition Bubbles in the Electroweak Phase Transition [PDF]
, 1995 The electroweak phase transition, if proceeding through nucleation and growth of bubbles, should generate large scale turbulent flow, which in turn generates magnetic turbulence and hence magnetic fields on the scale of turbulent flow.
