Embodiment

[0027] Example 1: Reference figure 1 This embodiment provides a physical wind tunnel consisting of five parts: stabilization section 1, contraction section 2, test section 3, diffusion section 4, and fan section 5 connected in sequence, and is based on an intelligent interactive platform to measure experimental data.

[0028] Reference figure 2 The stabilizing section 1 is composed of a first cavity wall 6 and a rectifying device 7 embedded in the first cavity wall 6. The first cavity wall 6 is composed of an aluminum alloy structural frame 8 and an aluminum alloy side wall 9. On the premise of comprehensive airflow uniformity, stability and airflow energy index, the rectifying device 7 adopts a three-layer gauze combination to reduce the vortex generated by the fan. The rectifying device 7 is composed of a cross-shaped fixed frame 10 and a metal wire mesh 11. After the metal wire mesh 11 is tensioned, the fixed frame 10 is pressed and fixed from both sides. The air inlet of th...

Abstract

The invention relates to a wind tunnel based on an intelligent interactive platform. The wind tunnel comprises a wind tunnel body and a measurement system. The wind tunnel body is direct-flow-type and is obtained through successively connecting a stable section, a contraction section, a test section, an expansion section and a fan section. The measurement system comprises electronic sensors, an Arduino board, an adapter board and data transmission planar packaged wires. The adapter board connects the anode, the cathode and clock signal end of each electronic sensor with corresponding ports of the Arduino board. Jump wires successively connect sequence ports of the electronic sensors with corresponding analog input ports of the Arduino board. The Arduino board is connected with a USB interface of a computer, thereby realizing data transmission. The electronic sensors are connected with a surface fixing layer in a tested model. The data transmission planar packaged wires are connected with the adapter board. The wind tunnel facilitates understanding of a complicated urban wind environment phenomenon and effect thereof on building performance by an architect and realizes early finding and settlement of designing problems in an early designing period. Furthermore the wind tunnel has an instructive meaning in improving building performance and energy efficiency.

Description

Technical field [0001] The invention mainly relates to the field of wind environment simulation, in particular to a wind tunnel based on an intelligent interactive platform. Background technique [0002] Understanding the phenomenon of air flow in a high-density urban environment is essential for architecture and urban design. The flow and diffusion of wind in the city determines the air quality of the environment, building wind pressure, urban heat island effect, and pedestrian comfort . The existing research methods of building wind environment can be basically divided into two categories: wind tunnel experiment and numerical simulation. Both methods have advantages and disadvantages. Among them, the wind tunnel experiment can truly simulate the wind environment phenomenon in the urban context, and accurately and effectively measure the relevant data. However, the construction and operating costs of traditional industrial-grade wind tunnels are too expensive and require profe...
