유동해석을 이용한 횡형 압력식 수영장 여과 시스템의 스트레이너 형상 변화에 따른 성능 연구

Abstract

As interest in the quality of life increases, public sports facilities as swimming pool are increasing. As interest in swimming increases, demand for swimming pools across the country is increasing. Therefore, there is also an increasing interest in the economic loss of water maintenance costs. This study aims to evaluate the performance of pool filters according to strainer shapes, which are important components of a pool filtration system, and to obtain data to help design pool filters in the future by analyzing internal flow fields. For the flow analysis according to the shape of the strainer, the magnitude of vector of the strainer part of the diagonal type model is larger than the vertical type model. It is showed that the model using an diagonal type strainer during backwashing will increase the expansion rate of the deposition and remove more contaminants from the filter medium. In this paper, it will propose an improved strainer shape during the filtration and backwash process of the swimming pool filtration system with comparison of the results of the strainer shape change and validate of the flow analysis results of the computational swimming pool filtration system.
