The possible states in the flow around two identical circular cylinders in tandem arrangements are investigated for configurations in the vicinity of the drag inversion separation. By means of numerical simulations, the ...

A general transition criterion is proposed in order to locate the core-annular flow pattern in horizontal and vertical oil-water flows. It is based on a rigorous one-dimensional two-fluid model of liquid-liquid two-phase ...

Purpose. To demonstrate the utility of 4D flow MR imaging for analyzing blood flow patterns and flow distribution in patients with congenital heart diseases. Methods: Six patients with congenital heart diseases were scanned ...

The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...

In this paper, it is analyzed two algorithms to calculate the three-phase power flow in electricity distribution networks. The algorithm should be able to present an effective convergence to unbalanced networks spending ...

This paper presents a comparative analysis of the influence of PV bus representation on the convergence characteristics of the Newton-Raphson Current Injection method. The methods used for solving the power flow problem ...
