Water and fertilizers use efficiency in grafted and non grafted tomato plants on soilless culture
(2008)
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 IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(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 ...
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
(2008)
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 ...
Fan and pad evaporative cooling system for greenhouses: Evaluation of a numerical and analytical model
(2008)
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 ...
Aspects of CFD Modelling of a Fan and Pad Evaporative Cooling System in Greenhouses
(2008)
A methodology approach to simulate, by means of computational fluid dynamics (CFD) tools, a greenhouse equipped with a fan and pad evaporative cooling system is presented. Using the main aspects of evaporative cooling ...
Numerical and experimental analysis of convective heat transfer in a heated greenhouse
(2008)
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 ...
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 ...
Thermal behaviour of a tunnel arc greenhouse during a solar day
(2008)
The present study investigates numerically the effect of transient solar radiation distribution during day-time in arc type tunnel greenhouse with continuous side vents and a tomato crop using a commercial CFD code. A two ...
Validation of a tomato crop simulator for Mediterranean greenhouses
(2008)
The aim of this work is the validation of the adaptation of the TOMGRO tomato crop simulation to short term cropping technique and to Greek conditions. Indeed, a current practice in plastic greenhouses in the Mediterranean ...
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 ...
