Abstract

A customized CFD simulator to perform thermo-fluid dynamic simulations of an HVAC for an indoor space is presented. This simulation system has been developed for engineers studying architectural engineering, as the HVAC mechanical systems used in housings and buildings. Hence, all functions and options are so designed to be suitable that they are suitable for non-CFD experts as well as CFD engineers. A Computational mesh is generated by open-source libraries, FEMM (Finite Element Method Magnetics), and OpenFOAM. Once the boundary conditions are set, the fluid dynamic calculations are performed using the OpenFOAM solver. Numerical results are validated by comparing them with the experimental data for a simple indoor air flow case. In this paper, an entirely new calculation process is introduced, and the flow simulation results for a sample office room are also discussed.

밀폐된 공간내의 공조 문제에 있어서 실내의 기류 및 온도 특성을 전산유체역학기법을 통해 쉽게 예측할 수 있는 맞춤형 시뮬레이터를 개발하였다. 본 시스템에서는 사용자가 직접 해석 대상 평면도를 입력하고 적절한 경계조건을 설정하면 전산유동해석을 위한 계산 격자가 자동으로 생성되고 유한체적법으로 이산화된 공개 전산유체코드를 통해 주어진 공간내의 열유체 해석 결과를 얻게 된다. 초기 실내 평면도면 입력부터 경계조건 설정, 전산유동해석 결과까지 하나의 사용자 인터페이스 상에서 작업할 수 있으며 격자생성과 유동해석 알고리듬은 공개 라이브러리를 사용하여 구현하였다. 간단한 실험 데이터를 통해 해석결과를 검증하였으며 실제 실내 공조에 대한 기류해석을 통해 유동의 경향성을 파악할 수 있는 맞춤형 유동전산모사 시스템을 구성하였다.
