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)). ...
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 ...
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 ...
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)
The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ...
