Experimental results of heat transfer coefficients in a mixer equipped with the reciprocating agitator are presented in the paper. Investigations showed the influence of different configurations of a new-type reciprocating agitator on heat transfer process. The data obtained were elaborated in a form of dimensionless correlations describing the effect of operating conditions and liquid axial flow.

Przedstawiono wyniki pomiarów wartości współczynnika wnikania ciepła w mieszalniku wyposażonym w mieszadło posuwisto-zwrotne. Na podstawie uzyskanych wyników pokazano wpływ konfiguracji geometrycznej testowanego mieszadła na proces wymiany ciepła. Dane opracowano w formie równania korelacyjnego uwzględniającego wpływ analizowanych warunków procesowych i przepływu mieszanej cieczy przez mieszalnik.
