Embodiment 1

[0085] A kind of simulation method of chicken house ventilation, its steps are as follows figure 1 As shown, the details are as follows:

[0086] (1) Obtain relevant information about the chicken house to be simulated; the chicken house to be simulated is located in a chicken farm in Dafeng District, Yancheng, central Jiangsu Province, China. Dafeng District faces the Yellow Sea in the east, and is located at 32°56'~33°36 north latitude ', east longitude 120°13'~120°56', belongs to the subtropical monsoon climate, the meteorological conditions monitored and simulated are early winter, and the outdoor air dry bulb temperature is 277.0K (4.0°C);

[0087] The specific structure and size of the chicken house to be simulated are as follows: figure 2 As shown, the chicken house is 128.000m long, 11.000m wide, 6.300m high, and 6.500m high on the curved roof. There are 18 fans for longitudinal ventilation evenly arranged on the western end wall, with a radius of about 0.700m. The t...

Embodiment 2

[0110] An electronic device, the structure of which is as Image 6 shown, including one or more processors, one or more memories, and one or more programs;

[0111] One or more programs are stored in the memory, and when the one or more programs are executed by the processor, the electronic device executes the same method for simulating chicken house ventilation as in Embodiment 1.

[0112] It has been verified that the simulation method for chicken house ventilation of the present invention can fully reflect the key factors affecting the ventilation of the chicken house, analyze the influence of each key on airflow organization, temperature distribution and window ventilation performance, and can realistically simulate the ventilation status of the chicken house; data The processing capacity is small, which can reduce the workload of modeling and actual measurement, the risk of epidemic prevention, and conveniently and quickly obtain engineering credible simulation results; i...

Abstract

The invention discloses a henhouse ventilation simulation method and electronic equipment applying the method. The simulation method comprises the following steps: acquiring geometric and physical information of a henhouse to be simulated; determining a control equation; establishing a three-dimensional physical model and dividing calculation grids; determining a spatial discretization method; determining calculation reference conditions and methods; defining material characteristics; determining a turbulence model and a near-wall flow processing method; defining surface boundaries and regionconditions; setting solving control parameters; initializing solving parameters; setting a residual error limit value and a monitoring parameter; solving a control equation, judging convergence, entering the next step if the convergence occurs, and otherwise, returning to the second step; displaying and outputting computational results. According to the method, consideration factors are comprehensive, the simulation degree is high, hardware requirements are low, the calculation speed is high, the speed, pressure, temperature and pollutant concentration distribution information in the henhousecan be known in detail, and the henhouse ventilation design level and energy utilization efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and relates to a simulation method for chicken house ventilation and electronic equipment using the method. Background technique [0002] The air environment of the chicken house includes parameters such as temperature, relative humidity, wind speed, pollutant composition and concentration. The first three parameters represent thermal comfort, and the latter parameters represent cleanliness. It is closely related to the welfare, disease, production capacity, epidemic prevention, feeding and operation management costs of poultry, the health of staff and surrounding residents, and even the global atmospheric environment. [0003] Recently, with the development of the poultry industry, the degree of intensification of chicken houses has become higher and higher, and the scale of farming has become larger and larger. Researchers have found that the thermal comfort of chicken houses is gettin...
