Podstawę do analizy procesu wrzenia stanowi wiedza o warunkach tworzenia się pęcherzyków i ich oderwania od powierzchni wymiany ciepła. Do wizualizacji procesu w miedzianej, włóknistej strukturze porowatej, pokrywającej rurowe powierzchnie zastosowano technikę szybkiego fotografowania. Do tego celu użyto kamery cyfrowej do szybkich zdjęć FT-1 oraz kamery cyfrowej CV-M40. Badania wymiany ciepła wykonano dla zmiennych parametrów włóknistego pokrycia (porowatości i grubości) i dla dużej objętości wody destylowanej, etanolu i freonu 123. Opracowano własne oprogramowanie, pozwalające na wyznaczanie średnic Dd i częstotliwości f odrywających się pecherzy parowych. Trzeci istotny parametr wrzenia tj. gęstość ośrodków nukleacji n obliczano analizuj...
