A DNS study of the rheology of dense suspensions in plane Couette flow

Dense suspensions can be found in various industrial and natural processes. A relatively new technique uses the principle of additive manufacturing to produce products from a wide variety of materials by printing with dense suspensions. To reach a high print quality the suspension rheology must be understood very well. Current knowledge about...

Simulating the Mechanically Induced Reaction of Energetic Materials: A Non-Linear Simulation of Finite Element Analysis

Munition articles may be sensitive to case-crushing loading. This is a potential safety hazard since it may lead to accidental detonation. A better understanding of the mechanism causing the munition articles to react can help improve safety. A finite element model combined with post-processing is used to model a Steven test. This thesis...

Effects of thermal hydrolysis process (THP) on struvite crystallisation from reject water of anaerobically digested sludge

Various technologies have been implemented in wastewater treatment plants (WWTPs) to generate clean effluent with minimised impacts on the environment. Thermal hydrolysis process (THP) and struvite crystallisation reactors are two examples of these technologies. THP generates humic-like substances, known as melanoidins, that are presumed to...
