following recent works of several authors like huilgol, bhattacharya etd. and javadpour et al., this paper is to contribute further to the literature of axial flow in a rotational coaxial rheometer. we consider axial flow of herschel bulkley mode1 between two concentric cylinders with the inner one rotating, while the outer cylinder is held stationary. an attempt has been made to direct the ana...

Two-phase flow patterns are critical in falling film heat devices. Hydrodynamic characteristics of turbulent films across a horizontal triangular tube bundle were studied under range Reynolds numbers and contact angles. A pattern map based on the k-means clustering approach was proposed after intercolumn two-phase grouped. The results demonstrated that liquid-vapor could be effectively reasonab...

A temporal stability analysis was carried out to model the atomization of a swirling viscous non-Newtonian annular liquid sheet emanating from an air-blast atomizer subject to inner and outer inviscid swirling air streams. The dimensionless dispersion equation that governs the instability of a viscous non-Newtonian annular liquid sheet under swirling air streams was obtained. Numerical solution...

OBJECTIVE To evaluate new echocardiographic modes in the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC). DESIGN Prospective observational study. SETTING University Hospital. SUBJECTS 15 patients with ARVC and a control group of 25 healthy subjects. METHODS Transthoracic echocardiography included cross sectional measurements of the right ventricular outflow tract, ri...
