The Rayleigh–Benard instability ... WebOct 29, 2024 · The instabilities, called the Richtmyer-Meshkov and Rayleigh-Taylor instability, respectively (RMI and RTI), adversely affect target implosion in experiments aimed at the achievement of nuclear fusion by inertial confinement by causing the nuclear fuel contained in a target and the ablated shell material to mix, leading to contamination …
Web1. Introduction. In the production of polymer films, uniformity in thickness and concentration is paramount. There are numerous physical processes that interfere with this desired result such as skin formation [1,2] and convective motion such as thermal Rayleigh-Bénard [] and Marangoni instabilities [4–8].These latter examples generate convective flow cells that …
