Continuous Thickening of Homogeneous Flocculated Slurries

Fully-continuous Supercritical Fluid Extraction of Naphthalene from Soil Slurries

The research objective was to build a fully-continuous lab-scale supercritical fluid extraction process to remove naphthalene from soil slurries. Both the carbon dioxide and the soil slurry were pumped into an extraction vessel simultaneously and continuously for the duration of an experimental run. Delhi Loamy Sand spiked with approximately 10 000 ppm (wt) of naphthalene and water comprised th...

Kinetic theory of shear thickening for a moderately dense gas-solid suspension: From discontinuous thickening to continuous thickening.

The Enskog kinetic theory for moderately dense gas-solid suspensions under simple shear flow is considered as a model to analyze the rheological properties of the system. The influence of the environmental fluid on solid particles is modeled via a viscous drag force plus a stochastic Langevin-like term. The Enskog equation is solved by means of two independent but complementary routes: (i) Grad...

Generalized Homogeneous Quasi-Continuous Controllers

A new class of arbitrary-order homogeneous quasi-continuous sliding-mode controllers is proposed, containing numerous functional parameters. All controllers also have robust outputfeedback versions. A numerical procedure is for the first time established for setting the controller parameters. A finite-time stable 5-sliding mode is for the first time demonstrated.
