Splet11. jan. 2024 · We present a solvable model inspired by dimensional analysis for the time-dependent spreading of droplets that partially wet a substrate, where the spreading eventually stops and the contact angle reaches a nonzero equilibrium value. We separately consider small droplets driven by capillarity and large droplets driven by gravity. Splet14. apr. 2024 · Furthermore, the distributions of 1000 samples at different time steps of the reduced dynamics are also compared with those of the original slow variable in Fig. 5. The reduced dynamics learned by Auto-SDE faithfully reproduces the slow dynamics of the original system so that we can learn multiscale dynamical systems effectively and …
Splet14. apr. 2024 · The total nursing time and mean nursing time per day were significantly longer after open partial nephrectomy (open 245.7 vs. 222.6 min, p = 0.025). With average nursing staff costs for a urological nurse of EUR 0.6061 per minute, the daily nursing costs were EUR 148.92 after open vs. EUR 134.92 after robotic partial nephrectomy ( Table 4 ). Splet21. feb. 2024 · In all cases, care was taken to (1) impose a minimal impact velocity at the coalescence event and (2) ensure the drops were of approximately equal diameter D at the time of coalescence (within...
SpletIn the sequel, we deal with the space-time discretization scheme adopted to approximate problem (i.e., ()), endowed with a wetting-drying interface tracking algorithm.In particular, both the spatial and the temporal discretizations of the domain Ω × (0, T] $$ \Omega \times \left(0,T\right] $$ will be driven by a mesh adaptation procedure detailed in Sections 3.4 …
Splet20. sep. 2011 · The wetting of solid surfaces by fluids has been studied for more than two centuries. However, it was only in recent years that investigations of the first milliseconds of spontaneous drop spreading on solid surfaces started. For non-deformable surfaces, this fast dynamic wetting process is known to be dominated by inertia and controlled by … short footstoolSplet01. feb. 2001 · We review the mechanisms controlling the dynamics of wetting in partial and complete wetting regimes.
