Flow Boiling Of Acetone In Parallel Rectangular Mini-Channels, Rafael Zimmermann

All Theses

Recent miniaturization of cooling systems has demanded better designing tools for compact heat exchangers. Forced two-phase flow through small channels is an effective way to better performance in a limited space. However, the characteristics of flow boiling in small channels differ from those in regular size channels, prompting a need for better understanding and development of predictive tools.
The characteristics of flow boiling in compact heat exchangers with parallel rectangular mini-channels of cross sections 0.50 x 0.50 mm, 0.75 x 0.75 mm, 1.00 x 1.00 mm, and 1.50 x 1.50 mm were experimentally investigated. Acetone was the fluid of choice, …
