Abstract

충전식 회전 원반 반응기에서의 흐름 형태를 50% 글리세린 수용액과 물감을 이용하여 조사하였다. 관찰에 의하면 반응기에서의 혼합여역은 유체가 원반과 같은 방향으로 회전하는 영역과 반대방향으로 회전하는 영역으로 나눌 수 있었고, 두 영역에서의 유체흐름은 난류이며 유체는 완전 혼합되었다. 반응기내 유체의 체류시간 분포를 설명하기 위하여 완전 혼합되는 2개의 영역과 샛길로 구성되는 3변수 다단모델을 설정하였으며 모델의 변수는 실험값과 Marquardt의 최적화 연산식을 이용하여 구했다. 모델은 실험값을 잘 대변하고 있음을 확인하였고, 체류시간 분포의 해석을 위한 관계식이 제안되었다.
The flow pattern in a rotating packed disk reactor was studied by using dye tracers in 50% glycerin solution. Based on the observation it was postulated that the fluid can be divided into two regions of mixing one region where fluid rotates in the same direction of the disk, and the other region where fluid rotates in the opposite direction. The fluide in the two regions were highly turbulent and perfectly mixed. A three-parameter multi-step model was adopted, with each step composed of two perfect mixing regions and a bypassing to illustrate the residence time distribution of fluid in the reactor. The parameters of the model were obtained from the experimental data, using Marquardt’s optimization algorithm. The model was in good agreement with the experimental data. Correlations were proposed for the analysis of residence time distribution.
