Numerical Analysis of the Wind Tunnel Effect on the Chinese Kang in the Northern China

Abstract:

In the northern part of China, the heating system of the Chinese kang occupies a significant proportion of usage, particularly during the winter. To achieve better heating effect, this article explored the wind tunnel (commonly known as the “dog hole”) of the Chinese kang in the Northern area. The paper conducted three experiments, established a two-dimensional mathematical model on the flow of high temperature gas in the chimney, utilized the FLUENT software to simulate the flow, and analyzed the inlet flow of the chimney flue and effect of wind tunnel on the heating system of Chinese kang. Wind tunnel was found to prevent natural reversed wind effectively and reduce the influence of outside wind.
