radiation and flow modeling的示例python代码

这里给您提供一个辐射传热的 Python 示例代码，使用的是 PyRadi 库：

import pyradi.thermal as thermal
import pyradi.ryplot as ryplot

# 定义一个黑体
emissivity = 0.9
temperature = 300  # K

# 定义两个板之间的间隙
gap = 0.002  # m

# 定义两个板的尺寸和温度
area = 1  # m^2
t1 = temperature
t2 = temperature + 10  # K

# 计算两个板之间的辐射传热
q = thermal.radiativeHeatTransfer(thermal.Tsurr(temperature), emissivity, area, gap, t1, t2)

# 打印结果
print(f'The radiative heat transfer is {q:.2f} W/m^2')

# 可视化结果
fig, ax = ryplot.createHeatMap(1, 1, 1)
ax.set_xlabel('Plate 1 temperature (K)')
ax.set_ylabel('Plate 2 temperature (K)')
qMatrix = thermal.radiativeHeatTransferMatrix(thermal.Tsurr(temperature), emissivity, area, gap, [t1, t2])
ryplot.plotHeatMap(fig, ax, qMatrix, [temperature, temperature + 10])
ryplot.showPlot()

这段代码计算了两个温度分别为 300K 和 310K 的平板之间的辐射传热，并可视化了结果。您可以根据自己的需求修改参数进行计算。
