Abstract
V delu so predstavljene izvedene meritve kritične gostote toplotnega toka pri podhlajenem mehurčkastem vrenju dielektričnega fluida FC-72, na horizontalno ležečih in vertikalno orientiranih, električno gretih grelnih trakcev, z različno obdelano grelno površino. Eksperimentalni del je potekal na merilni progi, na kateri so bili merjeni trakci, različno obdelanih površin pri nasičenem vrenju in pri različnih temperaturah podhlajenega vrenja. Dobljeni rezultati so pokazali naraščanje kritične gostote toplotnega toka z višanjem podhladitve. Trendna premica kaže linearno povečanje kritične gostote toplotnega toka s povečanjem podhladitve. Prikazani so rezultati vpliva strukturiranja površin grelnih trakcev ob doseganju kritične gostote toplotnega toka pri nasičenem in podhlajenem vrenju v primerjavi z neobdelanimi.

Title:Critical heat flux in subcooled pool boiling with dielectric fluid FC-72
Abstract:
In this work we investigated measurements of critical heat flux while performing subcooled pool boiling in FC-72 fluid, in horizontally laid and vertically oriented, electrically heated heating tapes, with differentlly processed heating surfaces. Experimental part took place on measurement track, where we measured different tapes in satured and subcooled boiling conditions. Obtained results showed linear increase of critical heat flux with enlargement of hypothermia in subcooled boiling in comparison with saturated boiling. We also showed effects on critical heat flux of processed surfaces on tapes in comparison with unprocessed tapes, while performing both, subcooled and saturated boiling.

Keywords:crititcal heat flux, subcool boiling, pool boiling, textured surface
