The Influence of Bicomponent Mixed Surfactants on Drop/Interface Coalescence
Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined. The drop size reduced appreciably and the multi-step coalescence was suppressed finally as the concentration of each of the constituting components</em...
متن کاملThermal delay of drop coalescence
We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference 1T0 between a drop and a bath of the same liquid. We characterize experimentally the dependence of the residence time before coalescence on 1T0 for silicone oils with different viscosities. Delayed coalescence arises above a critical temperature differ...
متن کاملOn the Variability of Drop Size Distributions over Areas
Past studies of the variability of drop size distributions (DSDs) have used moments of the distribution such as the mass-weighted mean drop size as proxies for the entire size distribution. In this study, however, the authors separate the total number of dropsNt from theDSD leaving the probability size distributions (PSDs); that is, DSD5Nt3 PSD. The variability of the PSDs are then considered u...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Drop size distributions of tropical rain over south India
Drop size distributions (DSD) associated with tropical rainfall at Cuddalore in the south-eastern part of India have been measured by a JossWaldvogel disdrometer (RD–80 model) during September to November 2002. The rainfall data corrected for instrumental error, matches very well with rainfall rates measured by a self recording raingauge, at the same site. For further analysis of the DSD, the r...
