The urban heat island (UHI) is one of the major problems that urban areas are experiencing worldwide, as it is related to various environmental and health effects. One of them is its direct impact on buildings energy demand. ...

Aim of the present paper was to present, analyze and compare detailed experimental data and CFD simulation results in a greenhouse equipped with insect screens. The studied greenhouse was a round arch type with vertical ...

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 ...

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 ...

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 ...

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. ...

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 ...

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 ...

Atmospheric pollutants from livestock operations influence air quality inside livestock buildings and the air exhausted from them. The climate that prevails inside the building affects human and animal health and welfare, ...
