Loading a dishwasher is one of those daily household chores that usually doesn’t involve too much thought; you pack the dishwasher with dirty crockery, remember to use detergent and then press the on button.
But there is more to loading a dishwasher than meets the eye as chemical engineers at the University of Birmingham, UK, in collaboration with industry, have conducted research on how best to load a dishwasher.
Dr. Raul Pérez-Mohedano, who led the project, published the group’s findings in the article, Positron Emission Particle Tracking (PEPT) for the analysis of water motion in domestic dishwasher, for Elsevier’s Chemical Engineering Journal.
The technique of Positron Emission Particle Tracking, developed at the University of Birmingham, was used to track and analyse the flow of water in the dishwasher through non-invasive 3D spatial detection of radioactively labelled particles i.e. tracers.
