A widely distributed spray is an important feature for atomizer which required in various applications such as gas cooling, turbine combustion, and fluidized bed granulator. Pressure-swirl example of provides a wide angle through the swirling effect inside atomizer. One parameters affecting geometrical constant, K. Another parameter pressure-swirl discharge coefficient, Cd. Discharge coefficien...

BACKGROUND Determinants of left atrial (LA) reservoir function and its influence on left ventricular (LV) function have not been quantified. METHODS AND RESULTS In an open-pericardium, paced (70 and 90 bpm) pig model of LV regional ischemia (left anterior descending coronary constriction), with high-fidelity LV, LA, and RV pressure recordings, we obtained the LA area with 2D automated border ...

Arterial compliance is found to be reduced in haemodialysis patients. It is not clear whether decreased arterial compliance in uraemic patients is a consequence of long-standing increased mean arterial blood pressure or a consequence of the uraemic state. An adequate blood pressure can be achieved by long-treatment-time dialysis of 8 h three times a week. We studied femoral and carotid artery w...

Butterfly valve is a flow control device, which is used to regulate the fluid flowing through a piping system. Analysis and optimization are of special importance in the design and usage of butterfly valves. A proper selection of a Butterfly valve would require the knowledge of its characteristics and robustness. Normally this information used to be obtained from experimental tests. However the...
