光伏玻璃温室自然通风条件下的CFD模拟验证

CFD Simulation and Verification of Photovoltaic Glass Greenhouse under Natural Ventilation Conditions

基于计算机流体力学(CFD)数值方法,以光伏连栋玻璃温室为研究对象,在自然通风的条件下对室内温度场进行模拟验证。采用离散坐标(DO)辐射模型对光伏温室室内温度场的时空分布和变化规律进行了三维CFD模拟和试验验证。结果表明,光伏温室室内温度试验结果和模拟结果绝对误差均值为0.96℃,相对误差均值为2.94%。模拟结果和试验结果吻合,验证了模型的可行性。

This study took the photovoltaic multi-span glass greenhouses as the object and validated temperature field inside by computational fluid dynamics （ CFD ） technology under the condition of nature ventilation .The 3 D CFD simulation and confirmation of the temperature field distribution and variation regulation were done with DO radiation model . The results showed that the absolutely mean error of experiment and simulation was 0.96＆#176;C,the relatively mean error was 2 .94%.The simulation results had an agreement with experiment results , which demonstrated the feasibility .
