Černetič, Blaž (author), Golobič, Iztok (mentor), Zupančič, Matevž (comentor)

Mehurčkasto vrenje je eden najbolj učinkovitih in hkrati inženirsko obvladljivih mehanizmov prenosa toplote, ki se ga izrablja na primer pri hlajenju jedrskih gorivnih palic, za hlajenje mikroelektronskih naprav in v separacijskih procesih. Vrenje ima tudi velik potencial za uporabo v vesoljski tehniki, zato se za simuliranje pogojev v vesolju izvajajo eksperimenti v paraboličnih letih, sondirnih raketah, stolpih na prosti pad in vesoljskih postajah. Eksperimentalni sistemi na paraboličnem letu morajo ustrezati veliko zahtevam s katerimi v laboratoriju nismo omejeni. V zaključnem delu so zbrane relevantne zahteve za eksperimentalne sisteme mehurčkastega vrenja pri paraboličnem letu. Pregledali smo podobne že zasnovane sisteme in z našimi izkušnjami izbrali ustrezne komponente glede na zahteve in priporočila za parabolični let. Ugotovljeno je, da je za naše potrebe najprimernejši fluid FC-72. Izdelali smo 3D model eksperimentalnega sistema z izbranimi komponentami, ki ustreza vsem predpisanim zahtevam.

• Title: Design of nucleate boiling experimental setup for parabolic flights

Abstract

Nucleate boiling is one of the most effective and simultaneously manageable to engineer heat transfer process that is for example used in cooling of nuclear fuel rods, for cooling microelectronics and in separation processes. Boiling also has a high potential for use in space applications, to simulate the conditions in space there different facilities such as parabolic flights, sounding rockets, droptowers and space stations. Experimental setups for parabolic flights must conform to many requirements that they do not need to in a laboratory. We gathered all the requirements applicable to experimental setup for nucleate boiling in parabolic flight. We chose our components based on previously designed similar experiments, our experience in nucleate boiling experimental setups and the parabolic flight requirements and recommendations. The most suitable fluid for our experiment was determined to be FC-72. With the chosen components, we made a 3D model of the experimental setup, which meets all given requirements.
