Analysis of Air-movement and Temperature Distribution in the Pad and Fan Cooling Greenhouse by Computational Fluid Dynamics (CFD)

Abstract

Characteristics of air-velocity and temperature distribution were discussed in the pad and fan cooling greenhouse by using computational fluid dynamics (CFD) techniques, in which term “volume porosity” and “surface permeability” virtually presenting the distributed solids such as the porous cooling pad were introduced into three dimensional, non-isothermal, turbulent κ-ε models.
The calculated results were validated by comparing with the observed data in the real flower culture greenhouse, and then the vertical and horizontal air distributions within the greenhouse were analyzed by using the visualized drawings.
