The removal of thick (approximately 1–10 mm) layers three viscoplastic soft-solid food-related materials (a moisturising cream, Biscoff spread and smooth peanut butter) from polymethylmethacrylate plates by turbulent, coherent, 2 mm diameter water jets was studied for jet velocities 10.6–25.4 m s −1 (10 500 < Re 25 400). When the layer thickness smaller than nozzle diameter, soil involved growt...

Abstract Local and integral characteristics of heat transfer are obtained at varying the Reynolds number Re = 5500, 11000, distance between jets y/D 1.8, from to surface z/D 0.5-10 for system two identical impinging jets. It is found in experiments that effect an adjacent jet leads enhancement local large distances nozzles barrier. also shown increase increases transfer, and, same time, weakens...
