Pressure drop characteristics of turbulent flow through 90 degree pipe bends are numerically investigated by computational fluid dynamic simulation using k-ε RNG turbulence model with standard wall function. After the validation of present model against existing experimental results, a detailed study has been performed to investigate the pressure distribution and pressure drop characteristics o...

PURPOSE To explore the potential relationship between optic disc haemorrhage, venous pulsation pressure (VPP), ocular perfusion pressures and visual field change in glaucomatous and glaucoma suspect eyes. MATERIALS AND METHODS This prospective observational study examined 155 open angle glaucoma or glaucoma suspect eyes from 78 patients over 5 years. Patients were followed with 3 monthly non-...

designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied together with design and build a low-speed wind tunnel. a specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. there are generally three regi...

Introduction: WH MRCA [1-4] examinations are usually performed during free breathing, and the Real-time Motion Correction (RMC) coefficient is important for obtaining good image quality. However, this coefficient differs in each patient, which may result in degradation of image quality. We have developed the Motion Pre-Analysis Method to determine the appropriate RMC coefficient before WH MRCA ...

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

Absorption coefficients of the carbon dioxide (CO2) were measured at atmospheric pressure and room temperature by photoacoustic technique with a cw, line-tunable, frequency stabilized CO2 laser. The CO2 laser spectrum of our system consists in 53 lines with wavelengths ranging from 9.2 μm to 10.8 μm and power levels below 5 W. Measured values of the CO2 absorption coefficients are typically of ...
