Ratio between Vena Contracta Width and Tricuspid Annular Diameter: Prognostic Value in Secondary Tricuspid Regurgitation [PDF]
Journal of the American Society of Echocardiography, 2021 Conventional approaches for the assessment of secondary tricuspid regurgitation (STR) severity do not correct for right heart dimensions. The authors hypothesized that STR severity can be proportional or disproportional to the dilation of the tricuspid annulus (TA) and investigated the prognostic impact of this novel definition.A total of 334 patients ...

Flow and Heat Transfer of Impinging Jet from Notched-Orifice Nozzle
Journal of Fluid Science and Technology, 2011 The centerline velocity of an orifice jet increases in the downstream direction from the nozzle exit and reaches a maximum of 1.2uce (where uce is the nozzle exit maximum velocity) at x/do≈2 (where do is the nozzle exit diameter) due to the vena ...

Lubricants, 2023 Mechanical seals, such as labyrinth seals, are typically installed at the turbine outlets to prevent oil leakage. However, these seals undergo deformation because of the vibrations of the rotor, even during normal turbine operating conditions, which may ...

, 2020 This paper presents the findings of a flume study using large-scale particle velocimetry (LSPIV) to estimate the top-width of the vena contracta formed by an approach open-channel flow entering a contraction of the channel. LSPIV is an image-based method

The Power-Velocity Integral at the Vena Contracta [PDF]
Circulation, 2000 Background —Noninvasive quantification of regurgitation is limited because Doppler measures velocity, not flow. Because backscattered Doppler power is proportional to sonified blood volume, power times velocity should be proportional to flow rate.

Aerospace, 2018 Detailed knowledge of jet plume development in the near-field (the first 10–15 nozzle exit diameters for a round jet) is important in aero-engine propulsion system design, e.g., for jet noise and plume infrared (IR) signature assessment. Nozzle exit Mach
