Download or read book Influence of fully miscible lubrication oil on flow boiling of CO₂ inside horizontal evaporator tubes written by Wetzel, Markus and published by KIT Scientific Publishing. This book was released on 2017-12-27 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow boiling heat transfer, pressure drop and flow pattern of CO?-POE oil mixtures were experimentally investigated in smooth and micro-fin tubes. The POE oil used features full miscibility in the range of operation investigated. The experimental data was evaluated based on mixture properties, used to evaluate and improve established predictive methods. The knowledge obtained contributes to understanding the influence of oil, which is essential for achieving an efficient evaporator design.
