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 ...

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 ...

Measurements of air exchange rates were performed in situ in a glasshouse equipped with a continuous roof opening. These measurements were carried out using the decay rate method with N2O as tracer gas. Simultaneously, ...

In this paper, the characterization and modelling of the most relevant convective transfers contributing to the elaboration of the greenhouse climate are reviewed. Convective transfers include heat and mass transfers between ...

The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ...

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 ...

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 ...

An analysis of the ventilation process in a tunnel greenhouse equipped with an insect-proof screen in the side openings was performed with the use of a commercial computational fluid dynamics (CFD) package (CFD2000®). The ...

The physical basis of natural ventilation is reviewed and the ventilation performance examined of six different greenhouse and tunnel types equipped with either roof or side, or both roof and side vents. Altogether, sixteen ...

Direct estimation of airflow at the vent opening by means of differential pressure measurements were performed in a twin-span greenhouse equipped with a continuous vent at the gutter. Application of Bernoulli's equation ...
