| Research Abstract |
The authors applied nonlinear high-carbon alcohol aqueous solutions, such as butanol and pentanol solutions, to boiling with impinging flow in T-shaped mini channel and compared dryout heat flux(CHF) with pure water. The geometry of the channel cross section was rectangular of 3mm x 3mm. It was found that the nonlinear aqueous solutions with impinging flow realized 2.0 to 2.4 times higher CHF than pure water. Thus, merit of the usage of those solutions was experimentally clarified.
