WebApr 13, 2024 · The negative relationship between the kurtosis for the acceleration in the y direction and the flow (OR = 0.741, p = 0.0072) indicates that, during a flow state, the acceleration in the y direction became more platykurtic, meaning that the tails of the distribution got heavier. This implies a heavier presence of the values further way from … WebApr 9, 2024 · We present spatially and temporally resolved velocity and acceleration measurements of turbulent Rayleigh–Bénard convection (RBC) in the entire fluid sample of square horizontal cross section with length \(L=320\) mm and height \(H=20\) mm, resulting in an aspect ratio of \(\Gamma =H/L=16\).The working fluid was water with a Prandtl …

WebDec 7, 2024 · Color flow Doppler is placed over the RVOT to detect flow acceleration or regurgitation. Then, using both continuous wave and pulse wave Doppler at the level of the pulmonary valve, velocities across the pulmonary valve in systole and diastole and peak velocities around the RVOT can be measured (figure 1 and image 1 and image 2). … WebFlow velocity. The solution of the equations is a flow velocity.It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the …
