Embodiment Construction

[0037] At present, there are two methods of quantitative analysis, wind tunnel test and computational flow dynamics (CFD). With the development of computer technology, CFD has been widely used in a cheap and convenient way.

[0038] CFD method formula

[0039] Indoor air flow density does not change much, the velocity is low, and due to the existence of walls, the viscosity of the air cannot be ignored, and the Reynolds number of indoor air flow often reaches the order of turbulent flow, so the indoor air flow is an incompressible turbulent flow. Its flow and heat transfer process can be expressed by the following general differential equations

[0040]

[0041] Among them, φ represents physical quantities such as flow velocity, temperature, and pollutant concentration distribution. For the corresponding turbulent flow model, φ also represents related turbulent flow parameters, such as turbulent kinetic energy and turbulent kinetic energy dissipation rate.

Abstract

The invention relates to a building design method based on wind speed streamline visualization. The building design method can be used for improving the windheat environment around a building, improving the campus comfort, and reducing the energy consumption of heating and refrigeration; by virtue of certain intelligent operations of a computer, wind speed vector distribution graphs of a wind speed streamline at different height can be obtained, and thus the building design method based on the wind speed streamline visualization is obtained. By virtue of the obtained wind speed vector distribution graphs, the distribution condition can be visually observed. According to the building design method, a middle school in the southern district of China is taken as an example, the wind environment condition of the reconstructed campus is researched; the building design method based on wind speed streamline visualization is used for surveying and researching the wind speed streamline to the greatest extent, better learning the important effect of the wind speed streamline in building design, facilitating building design and promoting harmonious coexistence of human beings and the nature.

Description

technical field [0001] The invention relates to the application field of computer technology, in particular to an architectural design method for visualizing wind speed streamlines. Background technique [0002] With the development of fluid mechanics, scientific computing visualization, computer graphics, and network 3D games, visualization technology has been widely used. Streamline visualization technology is a kind of vector field visualization technology, which mainly includes streamline calculation and flow line display. Because of its similarity with commonly used fluid experiment techniques, streamline visualization technology is widely used in computational fluid dynamics visualization, and the research on streamline visualization technology has become a very active topic in visualization research. However, the current streamline visualization technology is relatively slow in the speed of streamline construction, and it is not ideal in terms of the realistic effect...
