Air flow and associated sensible heat exchanges in a naturally ventilated greenhouse
Boulard, T.; Papadakis, G.; Kittas, C.; Mermier, M. (1997)In order to investigate the three-dimensional nature of the air flow within the greenhouse, a three-dimensional sonic anemometer was used for the direct measurement of air and heat exchange inside the greenhouse and through ... -
Air flow, temperature and humidity patterns in a greenhouse tunnel
Boulard, T.; Wang, S.; Haxaire, R.; Kittas, C.; Papadakis, G.; Mermier, M. (1999)Air distribution and climatic heterogeneity in greenhouses interfere with plants activity and influence largely crop activity and more particularly transpiration and photosynthesis. This is particularly true for the tunnel, ... -
The effect of vent configuration and insect screens on greenhouse microclimate
Bartzanas, T.; Katsoulas, N.; Kittas, C.; Boulard, T.; Mermier, M. (2005)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 ... -
Effect of vent opening and insect screens on greenhouse microclimate distribution
Kittas, C.; Katsoulas, N.; Bartzanas, T.; Boulard, T.; Mermier, M. (2006)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 ... -
Effect of Vent Openings and Insect Screens on Greenhouse Ventilation
Katsoulas, N.; Bartzanas, T.; Boulard, T.; Mermier, M.; Kittas, C. (2006)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 used to prevent insect intrusion on the ventilation rate of a round arch with ... -
THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
Kittas, C.; Katsoulas, N.; Bartzanas, T.; Mermier, M.; Boulard, T. (2008)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 ... -
Influence of an insect screen on greenhouse ventilation
Kittas, C.; Boulard, T.; Bartzanas, T.; Katsoulas, N.; Mermier, M. (2002)The influence of an insect screen on ventilation rate was experimentally investigated in a multispan glass-covered greenhouse equipped with a continuous roof vent, located at the University of Thessaly near volos in the ... -
Pressure field and airflow at the opening of a naturally ventilated greenhouse
Boulard, T.; Kittas, C.; Papadakis, G.; Mermier, M. (1998)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 ... -
Wind induced air exchange rates in a greenhouse tunnel with continuous side openings
Kittas, C.; Boulard, T.; Mermier, M.; Papadakis, G. (1996)To study the influence of wind speed on ventilation rates, experimental trials were carried out in a plastic tunnel with continuous side ventilators. This type of greenhouse is the most representative of Mediterranean and ...
