Study of mouthguard design for endurance and air-flow enhancement
… in term of stress distribution and air flow path by improving the pressure difference between the ambient (outside) and the oral cavity pressure (inside). A preliminary design has been study to simulate its total deformation and stress, in terms of Von Mises Stress by using ANSYS 15.0 …

Experimental and numerical study of flow characteristics and segregation in flow enhanced systems
… two major topics of importance are powder flow enhancement mechanisms and the flow characterization. This dissertation is involved with both of these topics. With respect to the powder flow enhancement, this study involves investigation of two types of flow enhancement methods. The first …

Studies of the Ethanol Steam Reforming Reaction in a Membrane Reactor
… permeances, and the highest ethanol conversion enhancement of 44 % and hydrogen molar flow enhancement of 69 % compared to a packed-bed reactor (PBR) were obtained in a MR fitted with a membrane with the highest hydrogen permeance. An operability level coefficient (OLC), defined as the ratio of …

Fabrication of Ultrathin Palladium Composite Membranes by a New Technique and Their Application in the Ethanol Steam Reforming for H₂ Production
… compared to the PBR. Average ethanol conversion enhancement and hydrogen molar flow enhancement were measured to be 12 % and 11 % in the Pd MR and 22 % and 19 % in the Pd-Cu MR, respectively. These enhancements of the conversion and product yield can be attributed to the shift in reaction …

CFD studies of complex fluid flows in pipes
The flow of rheologically complex fluids in industrial equipment poses a number of challenges, not least from a modelling point of view. Research is needed to further understand and be able to predict the flow behaviour of such materials and to investigate ways of improving their processing. This …

Measurement of The Vascular Input Function In Mice For Dce-Mri
… to artifacts associated with partial volume, inflow enhancement, and the limited temporal resolution achievable with MR imaging. In this work, the development of a suite of techniques for high temporal resolution, artifact resistant measurement of the VIF in mice is described. One obstacle in …
