The Effect of particle shape on just-suspended speed of mixtures of solids at high concentrations
Kütükçü, Başak; Ayrancı Tansık, İnci; Department of Chemical Engineering (2017)
Solid-liquid mixing is a common application in the chemical industry. For solid-liquid mixing operations, it is important to determine the impeller speed which provides the maximum contact surface between the phases at minimum power consumption. This impeller speed is called just suspended speed, Njs. Njs can be determined experimentally by visual observation or pressure gauge measurement method. If the mixing system is at the design stage or if it is not possible to apply experimental methods, the correlat...

The effect of curvature-scalar mixing on the annihilation cross sections of the dark matter scalar and unparticle dark matter
Iltan, E. O. (2011-12-01)
We consider the dark matter scalar in the Randall-Sundrum background and study the annihilation cross section if curvature-scalar mixing is switched on. In this case, in addition to the radion, the standard model Higgs scalar drives the annihilation, and it leads to considerable enhancement of the annihilation cross section. Furthermore, we take the unparticle, having a nonzero mass coming from the standard model Higgs-unparticle interaction at low energy levels, as a dark matter candidate and analyze the a...
