개요
A computational fluid dynamics (CFD) numerical model has been developed to effectively study the ventilation efficiency of multi-span greenhouses with internal crops, As the first step of the study, the internal plants of the CFD model had to be designed as a porous media because of the complexity of its physical shapes. 1n this paper, the results of the wind tunnel tests were introduced to find the aerodynamic
resistance of the plant canopy. The Seogun tomato was used for this study which made significant effects on thermal and mass exchanges with the adjacent air as well as intemal airflow resistance. With the main factors of wind speed, static pressure, and density of plant canopy, the aerodynamic resistance factor was statically found. It was finally found to be 0.26 which will be used later as an input data of the CFD model.
Moreover, the experimental procedure of how to find the aerodynamic resistancε of various plants using wind tunnel was established through this study.
