Greenhouse cooling by a fog system: Effects on microclimate and on production and quality of a soilless pepper crop
(2006)
The influence of greenhouse humidity control on greenhouse microclimate, crop transpiration rate, and yield and fruit quality of a soilless grown pepper crop was studied in a greenhouse located in the coastal area of western ...
THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(2008)
The objective of this work was to experimentally investigate the influence of vent type (side, roof, or both) and of anti-aphid insect screens on airflow, air temperature, and air vapor pressure deficit distribution in a ...
Effect of vent opening and insect screens on greenhouse microclimate distribution
(2006)
The objective of this work was to experimentally investigate the influence of vent type (side, roof or both) and of an anti-aphid insect screen on airflow and temperature distribution of a mono span greenhouse round arch ...
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
(2008)
In the present study a commercial CFD code was used in order to investigate the dispersion of a pesticide inside an arch type tunnel greenhouse with continuous side vents. The greenhouse was cultivated with a tomato crop ...
The effect of vent configuration and insect screens on greenhouse microclimate
(2005)
The influence of insect screens and vent configurations on airflow and temperature patterns in an arched plastic covered greenhouse used for cultivating tomatoes was analysed using a commercial computational fluid dynamics ...
Improving the efficiency of insect screens in greenhouses
(2009)
A CFD code was used in order to study the influence of different types of insect screens on greenhouse microclimate and natural ventilation performance. The validity of the code was checked against experimental data. The ...
Dispersion of pesticides from a naturally ventilated greenhouse: A CFD approach
(2006)
A methodology of application of a numerical technique in order to simulate the dispersion of pesticides from greenhouses is presented. The proposed simulation approach is based on preliminary calculations that concern the ...
Influence of whitening on greenhouse microclimate and crop energy partitioning
(2001)
The influence of whitening a greenhouse roof on microclimate and canopy behaviour was studied during summer in a greenhouse located in the coastal area of eastern Greece. Measurements of microclimate variables, intercepted ...
Crop-climate coupling in greenhouses. characterization and analysis
(2005)
The present work analyses the degree of coupling between a greenhouse rose crop and the internal climate as a function of crop characteristics (leaf area index, LAI) and greenhouse climate functions (natural and forced ...
Transpiration and energy balance of a greenhouse rose crop in mediterranean summer conditions
(2001)
The transpiration rate of a soilless rose crop and its interactions with the greenhouse microclimate and energy balance were investigated during summer conditions in Greece. At this aim, measurements of transpiration (γE ...
