The impact ofraindrops, which have a falling speed of 6−8 m sec−1(compared with, at most, 1 m sec−1for snowflakes), releases a large amount of kinetic energy (seePlate 4). Its effects are seen in the pounding action of heavy rain on exposed soil, and the splash in which ...
In the past three decades, the phenomena of drop impact on liquid surface attracted attention of many physicists [22–36]; however, only few studies are available on the formation of antibubble from a single drop while impacting on a bulk liquid surface. The formation of an antibubble from ...
Dynamic drop response of viscous Newtonian fluids is seen in applications such as inkjet printing10and spray cooling11. Adding a polymer to a simple viscous fluid can induce a non-Newtonian viscoelastic response that can greatly affect the dynamics of, e.g., pinch-off, surface impact, spreading...
Attention is focused on shear-thinning fluids, viscoplastic (or yield-stress) fluids, and viscoelastic fluids, in particular dilute polymer solutions.Bertola, VolfangoMarengo, MarcoDrops & Bubbles in Contact with Solid SurfacesV. Bertola, M. Marengo, Single drop impacts of complex fluids: a ...
Moreover, the selection of fitting function has an important impact on predicted performance. Although multiple nonlinear functions have been frequently employed as the fitting function, the optimal function is usually hard to find in this approach. 5.2.2 Based on numerical simulation Development of ...
Droplet impact on solid surfaces, a common occurrence, takes on specific significance in the realm of metal droplet deposition. Such interactions span various length scales across a wide range of fluids and substrates, playing a crucial role in diverse engineering applications. Notably, the deposition...
Subsequently, we apply XAI techniques to conduct ablation tests aiming to comparatively analyze which features exert a substantial impact on the coalescence of aqueous droplets in oil. 4.1. Implementation details In the modeling phase, the raw microfluidic droplet coalescence dataset is pre-processed ...

The technique yields in many cases results which are as accurate as these obtained by non-linear regression but also gives positive yield stress in cases where numerical schemes give negative yield stress values. It is shown that the impact of the values of the model parameters can be ...
