中文摘要:为分析单栋塑料温室内的温度场分布情况,建立了包括温室内外空间、室内作物和土壤层等的温室环境几何模型,在分析太阳辐射及各部分热交换的基础上,对单栋塑料温室内的温度场进行了3-D稳态模拟。热辐射传递过程采用蒙特卡罗法模拟,将室内作物简化为连续固体换热模型并采用剪应力输运模型表述空气紊流。结果显示:模型预测值均高于实测值,绝对误差均小于2.2℃,平均相对误差为6.7%。气流对温室内温度和均匀性影响较大,温室进风口侧的温度低于出风口侧。作物简化为连续固体的假设用于室内空气部分的温度预测具有一定的可行性,但预测值会高一些。

Abstract:To explore the temperature distribution in the simple plastic greenhouse of south China, a model was established including component of inner and outer space, inside plant and soil layer, etc. Based on analysis of solar radiation and heat exchange between different components, 3-D steady simulation of temperature distribution was carried out in greenhouse. The Monte Carlo model was adopted in thermal radiation and transfer process, shear stress transport (SST) model was used in air turbulence analysis, and the crop was simplified as continuum. The result showed that the value of simulation was a bit higher than that of the measurement. The absolute error was below 2.2℃ and relative error was 6.7%. The airflow had an obvious effect on temperature distribution and fluctuation, and the temperature of inlet side was lower than that of outlet side. It seems feasible to consider the crop as continuum in simulation model in this case, while the simulation value showed a bit higher. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
