Investigation of Internal Flow and Characteristic Instability of a Mixed Flow Pump
Volume 1: Symposia, Parts A, B and C, 2009The relationship between pump characteristic instabilities and internal flow was investigated in a mixed flow pump with specific speed of 700 (min−1 m3/min, m) or 1.72 (non-dimensional) by using a commercial CFD code and a dynamic PIV (DPIV) measurement.

Internal flow characteristics of simplex swirl atomizers
Journal of Propulsion and Power, 1985The influences of main dimensions and operating conditions of simplex swirl atomizers on the thickness of the annular liquid film formed at the discharge orifice are examined. A general expression for film thickness is derived which, when compared with the experimental measurements reported in the literature, shows very satisfactory agreement over wide

Postoperative flow characteristics of left internal thoracic artery grafts
The Annals of Thoracic Surgery, 1995Twenty patients whose left internal thoracic artery (LITA) was anastomosed to the left anterior descending artery (LAD) underwent postoperative coronary angiography and Doppler ultrasound velocimetry. During angiography, the diameter of the LITA conduit was measured at three points: proximal, mid, and distal.
