Method for the evaluation of minor losses in pulsatile laminar fluid flow
EPJ Web of Conferences, 2014 This article focuses on description and evaluation of the size of the minor losses in pulsatile laminar flow. It describes a method for determination of minor losses with respect to the phase delay between pressure waveforms and flow waveforms. The whole

Accumulating particles at the boundaries of a laminar flow [PDF]
Physica A: Statistical Mechanics and its Applications, 2007 The accumulation of small particles is analyzed in stationary flows through channels of variable width at small Reynolds number. The combined influence of pressure, viscous drag and thermal fluctuations is described by means of a Fokker-Planck equation for the particle density. It is shown that in the limit of vanishing particle size a uniform particle

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

Design of a laminar-flow-control supercritical airfoil for a swept wing [PDF]
, 1978 An airfoil was analytically designed and analyzed for a combination of supercritical flow and laminar flow control (LFC) by boundary layer suction. A shockless inverse method was used to design an airfoil and an analysis method was used in lower surface ...

AN EXTENSION OF THE FLOW BOILING CORRELATION TO TRANSITION, LAMINAR AND DEEP LAMINAR FLOWS IN MINICHANNELS AND MICROCHANNELS [PDF]
Proceeding of Compact Heat Exchangers and Enhancement Technology for the Process Industries - 2003, 2004 Flow boiling in mini- and microchannels offer very high heat transfer capabilities and find applications in many emerging technologies, such as electronics cooling and fuel cells. The low flow rate employed in such geometries, coupled with the small flow channels, often results in a laminar flow with all flow as liquid. Since the single-phase flow with

Changing of energy dissipation in the transition of laminar flow to turbulence (rus) [PDF]
Инженерно-строительный журнал, 2011 Under the same fixed dynamical boundary conditions the energy dissipation in laminar and turbulent flow are compared. As examples the flow past a plate and the flow through a pipe are considered.

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, EarlyView.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...
