Aerodynamic Resistance and Eddy Diffusivity above the Plug Stand under Artificial Light
인공광하에서 공정묘 개체군상의 공기역학적 저항 및 확산계수
Abstract
Experiment was performed in a newly developed wind tunnel with light system to determine the aerodynamic resistance and eddy diffusivity above the plug stand under artificial light. Maximum air temperature appeared near the top of the plug stand under artificial light. Since Richardson number was ranged from -0.07 to +0.01, the atmosphere above the plug stand in wind tunnel was in an unstable or near- neutral stability state. The average aerodynamic resistance at rear region of plug stand was 25 % higher than that at middle region. Eddy diffusivity(
