Solar radiation distribution in a tunnel greenhouse
(2008)
A commercial computational fluid dynamics code was used in order to investigate numerically the effect of solar radiation in an arc type tunnel greenhouse equipped with continuous side vents with a tomato crop. For the ...
INFLUENCE OF HEATING SYSTEM ON GREENHOUSE MICROCLIMATE DISTRIBUTION
(2010)
Convective and radiative heat transfer from heating systems significantly determines greenhouse microclimate during the cold period of the year. These mechanisms are complicated because they combine free and forced convection ...
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 ...
