The improved rooting environment and the absence of pathogens in substrates used in soilless cultures, make the use of grafted plants unnecessary when grown hydroponically. The worldwide water shortages and the increased ...

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 ...

The objective of this work was to experimentally investigate the influence of air mixing fans on air temperature and humidity distribution in an arched roof greenhouse. The greenhouse was occupied by a tomato crop and ...

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 ...

An experimental greenhouse equipped with fan and pad evaporative cooling is analysed using two different models. The first one consists of a numerical simulation approach applying a commercial CFD code. The main aspects ...

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 ...

Full-scale experimental data and computational fluid dynamics (CFD) methods are used to determine the accuracy of four different turbulence models [standard k-ε, k-ε renormalisation group (RNG), k-ε realisable, Reynolds ...

Internal convective flows, resulted from buoyancy forces, in a greenhouse tunnel were numerically and experimentally analysed and discussed. Experiments were performed in an experimental arc type tunnel greenhouse with a ...

The influence of greenhouse vent configuration on greenhouse microclimate and energy consumption when natural ventilation was used for greenhouse dehumidification was numerically analysed using a computational fluid dynamics ...

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 ...
