        논 엘레멘트 믹서의 혼합 메커니즘에 관한 수치해석적 검토

        유선호 ( Sun Ho You ) 한국분무공학회 2015 한국액체미립화학회지 Vol.20 No.1

        Visualization of the mixing pattern in a non-element mixer was carried out using laser induced fluorescence(LIF) to eval- uate characteristics of mixer consisting of the main flow pipe and branch flow pipes. The branch flows were injected peri- odically with the period Tin normal to the main flow, and rhodamine B was mixed into the most upstream branch flow to visualize mixing pattern in the main flow pipe by LIF. The length of boundary line L of the LIF image was measured. In this study, a numerical analysis was performed to identify the mixing process of the non-element mixer, and the results were compared with experimental results. Each result was almost the same. When the number of branch flows is increased, the mixing pattern became complicated and was supposed to become chaotic. The length of boundary line L increased exponen- tially with an increase in the number of branch flows.
