Abstract
Butanol aqueous solution is a promising useful liquid of boiling for the application of micro thermal devices because of high critical heat flux and small generating bubbles. In the past studies of the authors, boiling heat transfer has been investigated in various modes of boiling. Namely, fundamental features were studied by using horizontal heated wires and as for the application, flow boiling heat transfer was studied by using a mini-tube. The heat transfer on a flat surface has been also investigated in both steady and unsteady quench tests. In the present report, all the results are summarized and remaining problems are described.
