Exploration of Microclimate Physical Environment Based on Numerical Simulation—A Case Study of Shanghai Century Square

Abstract

Microclimatic factors cover flow, moisture and heat, and are interconnected and influenced. Isolated single factor studies ignore integrated natural processes; field-measured data collection is limited by the number of instruments. In this paper, the convective, moisture and heat coupling simulation of the winter and summer microclimate environment of Shanghai Century Square is carried out, covering more climate processes, calculating the simulation diagram of the tens of millions of grids, and converting the data into graphics. The reliability of the simulation data is verified by the measured data. Accurately reproduce the time course and spatial extent of the microclimate flow, plant cooling and humidification, water body heat transfer, and radiation. A plane diagram of climatic factor indicators at different time intervals in the daytime is plotted to analyze the regulation of spatial patterns on microclimate.
