Abstract
We applied butanol aqueous solution, pure water and propanol aqueous solution to boiling with impinging flow in mini channel and compared the result with each other. The butanol aqueous solution realized higher dryout heat flux than others. Besides, the boiling bubbles behaved differently depending on the kind of the solution. In the case of butanol aqueous solution, the boiling bubble became smaller and released from the heated surface more smoothly than others. On the other hand, we started to construct numerical model in order to analyze the distribution of concentration in the vicinity of the bubbles.
