光伏玻璃温室自然通风条件下的 CFD 模拟验证

摘要

This study took the photovoltaic multi-span glass greenhouses as the object and validated temperature field in-side by computational fluid dynamics ( CFD ) technology under the condition of nature ventilation .The 3 D CFD simula-tion 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°C,the relatively mean error was 2 .94%.The simulation results had an agreement with experiment results , which demonstrated the feasibility .%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。
