Design of Natural Ventilation and Analysis of Ventilation Safety in Commercial Building

Abstract:

This paper establishes computer CFD simulation mathematical model of large commercial buildings according to the principle of cubic interpolation function and determines the cubic interpolation function based on triangular elements method. It concludes the cubic polynomial in the process of simulation which improves the efficiency of computer simulation. This paper introduces modeling process and flow diagram of simulation process of numerical simulation of natural ventilation simulation of commercial building. It also simulates the indoor ventilation of building which treats the logistics field model of commercial tower building as the object of study. It concludes two-dimensional and three-dimensional contours of air and humidity. Finally, this paper gets the environmental distribution of the temperature through the simulation calculation and draws temperature change curve with distance which provides technical reference for the design of ventilation safe indoor.
