Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)
The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ...
Convective and ventilation transfers in greenhouses, part 2: Determination of the distributed greenhouse climate
(2002)
In this paper, the characterisation and modelling of the most relevant convective transfers contributing to the description of the distributed greenhouse climate are studied in detail. After a brief review of the equations ...
Leaf boundary layer conductance in ventilated greenhouses: An experimental approach
(2007)
Improving the design, control and management of greenhouse ventilation systems requires a better insight into the coupling and feedback mechanisms between the crop, the internal atmosphere and the outside atmosphere. The ...
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)
The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ...
Influence of greenhouse ventilation regime on the microclimate and energy partitioning of a rose canopy during summer conditions
(2001)
The influence of the greenhouse ventilation regime (natural or forced ventilation) on the energy partitioning of a well-watered rose canopy (Rosa hybrida, cv. First Red) was investigated during several summer days in warm ...
