Convective and ventilation transfers in greenhouses, Part 1: the greenhouse considered as a perfectly stirred tank
(2002)
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 ...
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 ...
Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)
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 ...
Influence of the heating method on greenhouse microclimate and energy consumption
(2005)
The influence of the heating system method on greenhouse microclimate was investigated overnight, using an experimental greenhouse tunnel with a tomato crop. The heating system consisted of plastic heating pipes located ...
Numerical simulation of the airflow and temperature distribution in a tunnel greenhouse equipped with insect-proof screen in the openings
(2002)
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(R)). ...
Convective and ventilation transfers in greenhouses, part 2: Determination of the distributed greenhouse climate
(2002)
In this paper, the characterisation and modelling of the most relevant convective transfers contributing to the description of the distributed greenhouse climate are studied in detail. After a brief review of the equations ...
Effects of a UV-absorbing greenhouse covering film on tomato yield and quality
(2012)
The effect of blocking the ultraviolet (UV) solar radiation using a UV-absorbing low density polyethylene (PE) film on tomato crop yield and fruit quality was evaluated in a two-year study in two arched roof greenhouses ...
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)
The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ...
Calibration and validation of a biological model to simulate the development and production of tomatoes in Mediterranean greenhouses during winter period
(2009)
The aim of this work is to calibrate and validate the adaptation of TOMGRO (TOMato GRowth), a crop growth simulation model for tomato, to the short-term cropping technique and to conditions in Greece. Current practice in ...
Extension and evaluation of a model for automatic drainage solution management in tomato crops grown in semi-closed hydroponic systems
(2015)
In the present paper, a model previously developed to simulate the course of Na+ accumulation in closed hydroponic systems as a function of plant water consumption was further extended so as to be operative also in semi-closed ...
