A numerical study with CFD has been carried out as to the air performance in the solar chimney equipment. The fluidity field and temperature field in the solar chimney were obtained, and the simulated temperatures were compared with measured temperatures. The results show that the flow rate of heated air increases from surrounding inlet radially to the center of the heat collector, and the temperatures decrease with the increasing of height from ground to chimney.

A numerical study with CFD has been carried out as to the air performance in the solar chimney equipment. The fluidity field and temperature field in the solar chimney were obtained, and the simulated temperatures were compared with measured temperatures. The results show that the flow rate of heated air increases from surrounding inlet radially to the center of the heat collector, and the temperatures decrease with the increasing of height from ground to chimney. To some extent, the simulated temperatures are in agreement with measured ones. However, the difference exists because some assumptions were applied in the numerical study. The simulated temperatures were symmetrical with the center of the geometry of collector due to steady assumption. But, with regard to the measured temperatures, the ones in the southern collector is higher than the ones in the northern collector, and the temperature peak moves to the south, not at the center of the collector, since the intensity of solar radiation is stronger on the southern collector than on the northern collector.

用Fluent软件对太阳能烟囱发电装置内的气流进行了数值模拟,获得了太阳能烟囱发电装置内气流流速、温度等分布,并将温度场模拟计算值和试验检测值进行了比较。结果表明:气流在集热棚中从四周向中部汇流是一个加速的过程;从地面到烟囱,随着高度的增加温度呈递减分布。温度分布模拟与试验检测结果的规律基本相似。但由于进行了稳态假设,也存在一定差别。数值模拟结果以集热棚中心呈对称分布。然而,由于集热棚南部接收的太阳辐射大于北部,在试验检测中南边的温度明显高于北边的温度,温度的峰值向南边偏移,呈不对称分布。

The first small-scale solar power chimney for power generation in our country has been constructed, a numerical simulation of flow field inside the said chimney being carried out, and comparison between calculated value of the temperature field simulation and measured value in the test being made, the results having difference, but having similarity. The results of simulation show that the output power and energy conversion efficiency of the said chimney increase along with increasing the area of heat-collecting shed and the height of the chimney.

建造了国内第一座小型的太阳能烟囱发电试验装置,并用FLUENT软件对该装置的流场进行了数值模拟,将温度场模拟计算值和试验检测值进行了比较,结果虽有差别,但有相似性。数值模拟结果表明,太阳能烟囱的输出功率及能量转换效率随集热棚面积和烟囱高度的增加而增加。

The temperature field of the place where locates steam-gas inlet at steam cooling leg of HP heater under steady state was simulated by using engineering software ANSYS.Two kinds of different thermal models were comparatively analyzed after the models were simplified and built.The distribution of temperature and temperature gradient of the pipe junction and shell was discussed based on calculation.Through the analysis,the places where were badly affected was presented,and relation between part structure inside...

The temperature field of the place where locates steam-gas inlet at steam cooling leg of HP heater under steady state was simulated by using engineering software ANSYS.Two kinds of different thermal models were comparatively analyzed after the models were simplified and built.The distribution of temperature and temperature gradient of the pipe junction and shell was discussed based on calculation.Through the analysis,the places where were badly affected was presented,and relation between part structure inside equipment and temperature distribution was understood.These could be references for future design and alteration of pressure equipment.

高压加热器的工作过程复杂,承受的汽水参数较高。这里利用ANSYS有限元分析软件,对高压加热器蒸冷段蒸气进口处进行稳态温度场的模拟,对两种热分析模型进行对比分析。根据计算结果,得出进口处接管和壳体在稳定工作状态下的温度和温度梯度的分布情况,从而找到热影响严重的位置和设备内件结构对温度分布的影响,为设备设计和改造提供参考。
