Flow Regimes and Thermal Patterns in a Subway Station
In this paper, three dimensional model of the subway station was built, a mathematical model was developed based on the standard k- e turbulence model, and computational fluid dynamics (CFD) simulations for the air conditioning systems were performed to clarify the conditions of the temperature fields. Comparisons were made between different cases of air-conditioning with varying passengers densities showing the degree of human comfort within the space in each case. Commercially available simulation software Fluent 6.3 is incorporated to solve conservation of mass, momentum and energy in the processing of air distribution, and to analyze turbulence affection combined heat transfer on air distribution. In this thesis work, the so-called standard k- e turbulence model, one of the most widespread turbulence models for industrial applications, was utilized. Basic parameters included in this work are air temperature, air velocity, relative humidity and turbulence parameters are used for numerical prediction of indoor air distribution.
