The swirling flow in a diffuser has been studied using the stereo PIV technique. DANTEC hardware and software were used for experiment. water pipe inlet set spinning by introducing tangential jet flow. Both piping of circular cross-section, however casing had rectangular (square) cross-section. plane measurement was located perpendicular to within diffuser. two cameras with Scheinpflug lens mou...

For the assessment of the left ventricle (LV), echocardiography has been widely used to visualize and quantify geometrical variations of LV. However, echocardiographic image itself is not sufficient to describe a swirling pattern which is a characteristic blood flow pattern inside LV without any treatment on the image. We propose a mathematical framework based on an inverse problem for three-di...

Rayleigh scattering temperature measurements were obtained in a turbulent reactive swirling coaxial jet discharged from a swirl-stabilized burner along the jet-flame centerline. They are reported up to 10 fuel nozzle diameters downstream of the burner exit at a Reynolds number of 29000. The effect of swirl numbers (S=0.3, 0.58, 1.07) on the temperature fields, the power spectral density of temp...

OBJECTIVES Chest ultrasonography is a useful diagnostic tool for the detection of pleural effusions of different etiologies. Our purpose was to determine whether the echogenic swirling pattern identifiable on real-time chest ultrasonographic images is a predictor of malignant pleural effusions in patients with malignancies. DESIGN Medical records of patients undergoing chest ultrasonography i...

This paper examines the manner in which heat release resulting from premixed combustion alters the nature of near-critical, axisymmetric, swirling flow in a straight circular pipe. Attention is confined to dilute premixtures so that exothermicity is weak and a small-disturbance approach applicable. The weak exothermicity is found to have a considerably larger effect on the flow. In the absence ...
