In this note, we introduce a microscopic model for the motion of gas bubbles in viscous fluid. By interpreting bubble as compressible fluid with infinite shear viscosity, derive pde/ode system coupling density/velocity/pressure surrounding linear/angular velocities and radii bubbles. We provide 1D analogue construct an existence theory simplified natural regularity framework. The second part pa...

Crystals are known to affect bubble behavior in natural and industrial melts. In volcanology, high crystal contents (?c > 30 vol.%) may drastically increase the suspension viscosity, altering dynamics severely enough modify eruptive style. During glass production, crystals can process final product. this work, we investigate how a small crystallinity of nano-sized RuO2 ? 2 modifies melt, genera...

Ultrasonic treatment is a suitable method for refinery processes that Acoustic cavitation technique allows high levels of energy to be released into the liquid, which leads changes in fluid properties such as decrease viscosity. Additionally, it's an effective way improve economic feasibility physicochemical processing enhance quality product. In this work, vacuum gas oil with viscosity 8.4 c.s...

The rates of passive degassing from volcanoes are investigated by modelling the convective overturn of dense degassed and less dense gas-rich magmas in a vertical conduit linking a shallow degassing zone with a deep magma chamber. Laboratory experiments are used to constrain our theoretical model of the overturn rate and to elaborate on the model of this process presented by Kazahaya et al. (19...

Data is presented for the vapor liquid equilibrium viscosity reduction of lubricants with two refrigerant blends at two temperatures. The lubricants tested were a 32 ISO VG mixed acid polyolester and a 32 ISO VG branched acid polyolester. The refrigerant blends used were HFC-125/143a/134a (44/52/4% w/w), and HFC-125/143a (50/50% w/w). INTRODUCTION This experiment detennined the vapor liquid equ...

The Ellenburger Group of the West Texas Permian Basin is part of a Lower Ordovician carbonate platform sequence that covers a large area of the United States. During the Early Ordovician, the Permian Basin area was located on the southwest edge of the Laurentia plate between 20° and 30° latitude. The equator crossed northern Canada, situating Texas in a tropical to subtropical latitude. The are...
