运用 k- ε紊流模型对空调硬座车内三维流场和温度场进行了数值模拟。将人体散热和太阳辐射作为能量方程的附加源项 ,采用有限容积法和交错网格将计算区域进行离散 ,用 SIMPL E算法计算了空调硬座车内空气流动与传热问题。研究结果为空调车内气流组织的优化设计和舒适性评价提供了依据。
The k-ε turbulence model is used to simulate the 3D flow field and temperature field in the air-conditioned hard-seat vehicle. Taking body heat dissipation and solar radiation as additional sources of energy equations, the finite volume method and the staggered grid are used to discretize the calculation area. The SIMPL E algorithm is used to calculate the air flow and heat transfer problems in air-conditioned hard-seat vehicles. The research results provide the basis for the optimization design and comfort evaluation of airflow in air-conditioned vehicles.
