The paper presents the results of experimental studies critical heat flows in vertical small diameter channels, when coolant moves from bottom to top, which were carried out Obninsk branch MEPhI 1970s last century but have not become widespread due lack demand for their practical use. Nowadays, interest such works is manifested, first all, development compact plants and devices, particularly nu...

This paper deals with research into pool boiling critical heat flux (CHF) of water–Al2O3, water–TiO2 and water–Cu nanofluids on horizontal stainless steel tubes. The experiments were conducted under atmospheric pressure. Nanoparticles tested at concentrations 0.001%, 0.01%, 0.1% 1% by weight. Ultrasonic vibration was used in order to stabilize the dispersion nanoparticles. Although dispersants ...
