Computational fluid dynamics applications to improve crop production systems
(2013)
Computational fluid dynamics (CFD), numerical analysis and simulation tools of fluid flow processes have emerged from the development stage and become nowadays a robust design tool. It is widely used to study various ...
Experimental results and spatial simulation of climate in a greenhouse with insect screens
(2011)
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 ...
Solar radiation distribution in screenhouses: A CFD approach
(2012)
In this paper the effect of solar radiation distribution in a typical screenhouse was numerically investigated, taking into account the thickness and aerodynamic properties of the screen and its spectral, optical and thermal ...
Numerical and experimental assessment of the airflow field and ventilation rates in a naturally ventilated free cubical cattle house with large openings
(2013)
An efficient natural ventilation system in dairy cattle buildings is essential both for animal welfare and for environmental issues since the naturally ventilated livestock buildings are a major source of greenhouse gas ...
Pepper crop production under shading and insect proof screenhouses
(2014)
Aim of this study was to experimentally investigate the effect of three different shading and insect proof nets on pepper crop development and production. Three screenhouses were used; two of them were covered by a 50 mesh ...
Alteration of NO - 3, PO 3- 4 and SO 2- 4 Concentration on rose plants in response to greenhouse climate parameters and their concentration in the nutrient solution
(2011)
The objective of this work was to quantify temporal changes of NO - 3, PO 3- 4 and SO 2- 4 concentration on leaves, shoots and roots of rose plants during a short growing period, in response to air temperature, light ...
Characterization and analysis of the effects of greenhouse climate control equipment on greenhouse microclimate and crop response
(2011)
An overview of the recent scientific and technical advances on issues concerning the greenhouse microclimate, control and management in Mediterranean regions is presented and discussed. Special emphasis is given on the ...
Use of a decision support system for management of the drainage solution in semi-closed hydroponic systems under different drainage fractions
(2014)
Soilless cultivation, especially in closed-loop hydroponic systems offers a great option for water saving in greenhouses. Capture and recycling of the excess irrigation water that drains out of the root zone is possible ...
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Evaluation of crop reflectance indices for greenhouse irrigation scheduling
(2012)
Development of direct, non-contact, non-destructive methods for irrigation control purposes is of great interest. The present work deals with the evaluation of reflectance indices for irrigation control in greenhouse ...
