Positron emission particle tracking - a technique for studying flow within engineering equipment

Characterising porosity of multi-component mixtures in rotary mills

“…The only viable option then is to use non-invasive techniques. Non-invasive methods include: high-speed video and image processing tools (Santomaso et al, 2003), X-Ray (Govender et al, 2001), PEPT (Parker et al, 1993), and numerical methods such as discrete element methods (DEM). In what follows, selected studies done on particle packing in rotating drums are reviewed.…”

“…The positron emission particle tracking (PEPT) is a measurement technique developed at the University of Birmingham in the United Kingdom (Parker et al, 1993). It is a variant of the positron emission tomography (PET) that is commonly used in studying metabolic process in medical diagnostics.…”

“…In addition, 18 F decays only by positron emission and, therefore, has no interfering γ-rays (Parker et al, 1993). Other possible radionuclide include: 61 Cu and 66 Ga.…”

“…This camera was designed for the application PET to engineering studies. Descriptions of the camera can be found in Hawkesworth, et al (1991) and Parker et al (1993Parker et al ( , 1994. The camera consists of a pair of multi-wired proportional chambers, operated in coincidence.…”

“…This is done via a location algorithm, which has been discussed quite extensively (Hawkesworth et al, 1991;Parker et al, 1993Parker et al, , 1994Parker and Fan, 2008).…”
