摘要

在哥伦比亚，玫瑰（Rosa sp.）大多在自然通风的温室中种植。这项工作的目的是通过使用有限体积的CFD（计算流体动力学）软件对气流进行数值建模，从而对温室内产生的小气候进行表征。通过实验数据收集和实验与模拟数据的比较结果验证了所使用的CFD-3D模型，表明温度和相对湿度变量具有适当的调整程度和相同的趋势。结果表明，在白天条件下，产生的小气候处于玫瑰生产的最佳范围。对于夜间气候条件，观察到温室室内空气中存在热反转现象，这为植物的生长和发育创造了次优条件。

SIMULACION DEL MICROCLIMA EN UN INVERNADERO USADO PARA LA PRODUCCIÓN DE ROSAS BAJO CONDICIONES DE CLIMA INTERTROPICAL

In Colombia, roses (Rosa sp.) are mostly cultivated in naturally ventilated greenhouses. The objective of this work was to develop a characterization of the microclimate generated inside a greenhouse through the numerical modelling of air flows by using the CFD (Computational Fluids Dynamics) software of finite volumes. The CFD-3D model used was validated through experimental data collection and the results obtained from the comparison of experimental and simulated data, which showed a suitable degree of adjustment and the same tendency for the variables of temperature and relative humidity. The results obtained show that, for daytime conditions, the microclimate generated is in optimal ranges for the production of rose. For night-time climate conditions, presence of thermal inversion phenomenon in the indoor air of the greenhouse was observed, which generates suboptimal conditions for the growth and development of plants.
