摘要
为了深入研究北方寒冷干旱地区日光温室的温度场特性,本文从试验和基于CFD的温度场模拟的角度,对日光温室内全天的内部温度变化情况进行试验研究,试验及模拟结果表明,模拟结果与实际中测量得到的试验结果相吻合,误差在5%以内,很好地模拟了实际温室的温度场的分布情况。为了保证温室作物的正常生长温度的要求,需要根据当时的温度和太阳的辐射强度同时进行判定进而合理调整盖帘起落的时间,从而能够更好的保证作物的生长要求,对实际温室的使用和控制具有一定的指导意义。
Temperature filed of solar greenhouse in cold arid area was studied intensively through testing and the theory of CFD.Temperature variation of the inner greenhouse in a whole day was researched,it was concluded that simulation results were similar to test results,the residual was less than 5%,the CFD model described temperation distribution precisely. The moment of mat covering was adjusted accroding to local temperature and solar radiation in order to meet the request of normal growth of indoor crop. It could guarantee the growth of plant and direct the actual production.
