Modeling Liquid Slugs Accelerating in Inclined Conduits
Korzilius, Stan P.; Tijsseling, Arris S.; Bozkuş, Zafer; Anthonissen, Martijn J. H.; Schilders, Wil H. A. (ASME International, 2017-12-01)
In this article, we simulate traveling liquid slugs in conduits, as they may occur in systems carrying high-pressure steam. We consider both horizontal and inclined pipes in which the slug is accelerated by a suddenly applied pressure gradient, while at the same time, gravity and friction work in the opposite direction. This causes a steep slug front and an extended slug tail. The shapes of front and tail are of interest since they determine the forces exerted on bends and other obstacles in the piping syst...
Modeling binary CO2/CH4 flow through coal media
Gumrah, F.; Balan, H. O.; Atay, M. U. (Informa UK Limited, 2008-01-01)
CO2 can be sequestered in coal seams considering the environmental issues. By means of injecting CO2 into the coal seams, both sequestration of CO2 and the enhanced recovery of methane inside the coal seam can be realized. One-dimensional simulation regarding the binary CO2/CH4 flow in a coal seam core was studied by using an analytical solution method. The simulation results were compared with experimental data by matching the effluent concentrations of CO2 and CH4. The transport parameters such as longitu...

Solidliquid extraction of resveratrol and viniferin from grape cane samples was described by using first-order kinetic model, Peleg's model, two-site kinetic model and modified Gompertz equation. Goodness of fits of the models were evaluated by comparing the adjusted determination coefficient and root mean square error and mean percentage error values. Although the two-site kinetic model with four parameters described the data better, Peleg's model, with only two parameters, could explain the data with a sl...
