Thermal behaviour of a tunnel arc greenhouse during a solar day
(2008)
The present study investigates numerically the effect of transient solar radiation distribution during day-time in arc type tunnel greenhouse with continuous side vents and a tomato crop using a commercial CFD code. A two ...
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Study of a passive solar heating greenhouse crop grow gutter
(2011)
Water-filled transparent polyethylene tubes have been used as a passive solar system in greenhouses in Greece. In this work, the performance of a passive solar heating system used to serve as a crop grow gutter is studied. ...
Investigation of flow patterns in a greenhouse with mechanically assisted ventilation
(2011)
In the present work, the effect of fan ventilation in an arc type tunnel greenhouse under the encumbering action of solar radiation is studied. Results are accrued for the air velocity, temperature, pressure, vapour and ...
Flow characteristics and temperature patterns in a fan ventilated greenhouse
(2008)
The effects of solar radiation distribution during fan ventilation in an arc type tunnel greenhouse in various hours of daylight were numerically investigated. Inside the greenhouse there was a tomato crop 1.5 m tall. For ...
Efficiency of physical means of IPM on insect population control in greenhouse crops
(2011)
The efficiency of insect screens and photoselective covering materialson insect population control was experimentally evaluated. The experiments were performed from 2000 to 2004 in three greenhouse tomato, PE-covered ...
