Budi Kristiawan,Ahmad Imam Rifa'i,Koji Enoki,Agung Tri Wijayanta,Takahiko Miyazaki,Takahiko Miyazaki +5 more
TL;DR: In this article, a hybrid method with a microfin tube and TiO2/water nanofluid with various nanoparticles concentration has been investigated experimentally, and the objectives of this work are to characterize thermohydraulic including friction factor and thermal performance, and to develop correlation based on the experimental result.
Journal ArticleDOI
Systematic measurements of heat transfer characteristics in saturated pool boiling of water-based nanofluids
TL;DR: In this paper, the authors investigated the heat transfer characteristics in saturated pool boiling of water-based nanofluids and found that the wall superheat likely to increase significantly when the nanoparticle layer formed on the heated surface is partially detached.
Journal ArticleDOI
Water flow boiling heat transfer in vertical minichannel
TL;DR: In this paper, the authors presented the results of an experimental investigation into the water boiling heat transfer in a minichannel conduit vertically oriented with the upward flow, and the authors used a flow pattern map with the vapor quality as the abscissa versus the mass velocity as the ordinate.
Journal ArticleDOI
Heat Transfer Enhancement of TiO2/Water Nanofluids Flowing Inside a Square Minichannel with a Microfin Structure: A Numerical Investigation
TL;DR: In this article, a combination of two passive heat transfer enhancement techniques using a microfin structure and nanofluids was investigated numerically, and it was shown that the heat transfer can be increased by using only a nanoprocessor with a volume fraction of 0.01%.
Journal ArticleDOI
Measurement of the maximum bubble size distribution in water subcooled flow boiling at low pressure
TL;DR: In this article, the bubble nucleation process in water subcooled flow boiling at low pressure was observed in detail using an ITO-deposited transparent glass plate as the heated surface.
