The velocity boundary condition at the liquid–gas interface is more complicated: Since the process is assumed to be quasi-stationary, the interface of the mesh does not move during the solution procedure.
WebJul 7, 2015 · Marangoni convection — also called thermocapillary convection — is important in a number of processes, including welding, crystal growth, and electron beam melting. … WebApr 12, 2024 · In another study, Murata et al. [ 32] reported that the Marangoni force could drive the movement of silicone oil and water droplets from the low-temperature side to the high-temperature side, and investigated the relationship between the movement velocity, droplet size, contact angle, and temperature gradient.
WebIn the mid-1860s, Marangoni found the phenomenon that the natural convection dominated by liquid gravity gradually disappeared in a microgravity environment, whereas at the … WebJun 12, 2024 · The velocity of a Marangoni flow is proportional to the evaporation rate ( 28 ), and the alignment of collagen fibers self-assembled under flow depends on the flow-induced shear rate ( 25 ). Therefore, we hypothesized that we could tune the alignment of collagen fibers by varying the RH and thus the evaporation rate.
