Abstract

In this study, the flow characteristics happening inside water tank due to the configuration of various water tank were analyzed by using a computation fluid dynamics program, ANSYS CFX. This study also examined which model was most efficient at the flow by changing the flow conditions of the inlet and outlet due to the configuration of various tank. Same material was applied to models A, B and C. As the result of flow analysis, it was shown that model B had the best flow and model C had the highest pressure applied to the flow. So, though the water tank has the same material according to the configuration of product, the velocity and pressure of flow become different. Therefore, it is thought to develop the tank good for the fluid flow due to the product configuration through this flow analysis result. On the basis of this study result, the esthetic sense can be shown as the analysis data of flow due to the configuration of fluid tank are grafted onto the real life.

본 연구에서는 다양한 물탱크의 형상에 따른 입출구의 유동 조건들에 따른 물탱크 내부에서 발생하는 유동특성을 전산 유체 역학 프로그램인 ANSYS CFX를 이용하여 분석하였다. 또한 다양한 물탱크의 형상에 따른 입, 출구의 유동 조건들에 변화를 주어 어떤 모델이 가장 효율적인지를 알아보았다. 모델 A, B, C에 같은 재질을 적용하였다. 유동해석 결과로서는 모델 B가 가장 좋은 유동의 속도를 보이고, 모델 C는 유동에 가해지는 압력이 가장 높은 것으로 나타났다. 이로써 물탱크가 제품의 형상에 따라 같은 재질을 가지더라도 그 유동 속도와 압력은 달라졌다. 따라서 본 유동해석 결과를 통하여 제품의 형상에 따라 유동의 흐름에 좋은 탱크를 개발 할 수 있다고 사료된다. 본 연구 결과를 토대로 유체 탱크의 형상에 따른 유동의 해석 데이터를 실생활에 융합하여 그 미적 감각을 나타낼 수 있다.
