Original abstract
Experimental work was concentrated on the study of descaling in relation to heat transfer and the quality of removing scale from the surface. Three types of measurements were implemented. The first one is a measurement of impact pressure distribution on spraying surface. The second is a measurement of temperature drop when a product is passing under the nozzle. The third type is a study of the surface quality where a defined layer of oxides is sprayed and its remaining thickness is evaluated. The heat transfer test is evaluated by inverse task and the results are prepared in a form of boundary conditions suitable for using in a numerical model.
Czech abstract
Experimentální práce byla zaměřena na studium odstraňování okují v závislosti na přenosu tepla a kvalitě odstranění okují z povrchu. byly provedeny 3 druhy měření. První měření rozložení dopadu tlaku na ostřikovaný povrch, druhé bylo měření teplotní kapky v momentě kdy produkt dopadu prochází pod tryskou. Třetí bylo studium kvality povrchu, kdy je vrstva oxidu ostřikovaná a její zbytková tloušťka je změřená. Test přenosu tepla je vyhodnocen inverzní úlohou a výsledky jsou připraveny ve formě okrajových podmínek vhodných pro numerický model.
