WebApr 20, 2012 · It is demonstrated that the VOF method can correctly predict the breakup of thins films into an array of either axisymmetric droplets or clam-shell droplets, depending on the surface energy. The well-known phenomena of Plateau-Rayleigh instability has been simulated using computational fluid dynamics (CFD). The breakup of a liquid film into an … WebJul 29, 2024 · Jets––cylindrical streams of fluid—can form transiently at higher fluid velocities, yet interfacial tension rapidly drives jet breakup into droplets via the Rayleigh–Plateau instability. Liquid metal is an unlikely candidate to form stable jets since it has enormous interfacial tension and low viscosity.

WebN2 - This paper presents a new method to produce monodisperse supercooled refrigerant droplets, comparing the breakup mechanism to the Plateau-Rayleigh instability. Formulations of highly volatile species, HFA134a and HFA152a, are cooled to 230K to form a steady unstable liquid column. WebFeb 2, 2011 · Rayleigh (1878) was among the first to study theoretically the breakup of liquid jets. He considered the simple situation of a laminar jet issuing from a circular orifice and postulated the growth of small disturbances that produce breakup when the fastest growing disturbance attains a wavelength λ opt of 4.51 d, where d is the initial jet diameter. cyxtera ord2 location

WebNov 1, 2011 · Physics of jet breakup are well known, on a macroscopic point of view, since a long time. As shown in Fig. 1, four breakup modes can be distinguished.First, the Rayleigh … WebThe Kelvin-Helmholtz and Rayleigh-Taylor (KH-RT) breakup models were employed for the primary and secondary atomization of spray droplets [28]. In addition, the Dukowicz … The linear stability of low viscosity liquids was first derived by Plateau in 1873. However, his solution has become known as the Rayleigh-Plateau instability due to the extension of the theory by Lord Rayleigh to include fluids with viscosity. Rayleigh-Plateau instability is often used as an introductory case to hydrodynamic stability as well as perturbation analysis. Plateau considered the stability of a thread of fluid when only inertial and surface tension effect… cyxtera ord2
