Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
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
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
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 ...
Dispersion of pesticides from a naturally ventilated greenhouse: A CFD approach
A methodology of application of a numerical technique in order to simulate the dispersion of pesticides from greenhouses is presented. The proposed simulation approach is based on preliminary calculations that concern the ...
Analysis of airflow through experimental rural buildings: Sensitivity to turbulence models
Full-scale experimental data and computational fluid dynamics (CFD) methods are used to determine the accuracy of four different turbulence models [standard k-ε, k-ε renormalisation group (RNG), k-ε realisable, Reynolds ...
Measurements and modelling of tracer gas distribution in a naturally ventilated greenhouse for pesticide dispersion determination
In this study numerical and experimental results concerning the dispersion of a tracer gas (N2O) inside an experimental greenhouse with a tomato crop were presented and analyzed. The proposed simulation concerns a greenhouse ...
