Interfacial interactions and mass transfer at the interfacial region of bituminous hydrocarbon mixtures

The adhesion between bitumen and aggregate is a complex process with numerous of variables. To improve the understanding of the bond between bitumen and aggregates in road applications, this research focuses on preferential adsorption, which is one aspect of bitumen-aggregate adhesion. The main objective is to find out whether there is...

Detailed simulations of liquid and solid-liquid mixing: Turbulent agitated flow and mass transfer

This thesis aims at a contribution to reliable and accurate predictions of complex, multi-phase processes. The reader is presented detailed simulations on liquid and solid-liquid mixing using large eddy simulations (LES) including scalar mixing and particle transport in a Rushton turbine stirred tank geometry. Large eddy simulations have been...

Fluidized bed ice slurry generator for enhanced secondary cooling systems

Ice slurries are liquid solutions of a freezing point depressant in water, in which small ice crystals are present. Ice slurries are efficient secondary cooling fluids because they utilize the latent heat effect involved with the ice/water phase change. A high heat capacity is available at relatively constant temperatures, while ice slurries are...
