Research description
This project investigates fundamental aspects of cleaning of soiled surfaces by the use of impinging jets such as those generated by spray balls for cleaning the internals of reactor and storage vessels. The fluid mechanics of jet conformation, spreading on impact, and drainage to give falling films will be studied at different length scales in the laboratory, and compared with recent mathematical models for jet impingement and rivulet flows. The effect of surface properties and contact angle will be studied using different surfaces, including coated surfaces, and the results related to real food fouling layers. These results will be compared with industrial cleaning operations performed at the industrial collaborators.
Cleaning also involves contact time and solvent action: these will be studied in separate, well-controlled studies and combined with the fluid flow results to yield a predictive model.
