Analysis of airflow through experimental rural buildings: Sensitivity to turbulence models
Bartzanas, T.; Kittas, C.; Sapounas, A. A.; Nikita-Martzopoulou, Ch (2007)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 ... -
Aspects of CFD Modelling of a Fan and Pad Evaporative Cooling System in Greenhouses
Sapounas, A. A.; Bartzanas, T.; Nikita-Martzopoulou, C.; Kittas, C. (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 ... -
Dispersion of pesticides from a naturally ventilated greenhouse: A CFD approach
Bartzanas, T.; Katsoulas, N.; Kittas, C.; Sapounas, A. A. (2006)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 ... -
Fan and pad evaporative cooling system for greenhouses: Evaluation of a numerical and analytical model
Sapounas, A. A.; Nikita-Martzopoulou, Ch; Bartzanas, T.; Kittas, C. (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 ... -
Measurements and modelling of tracer gas distribution in a naturally ventilated greenhouse for pesticide dispersion determination
Kittas, C.; Bartzanas, T.; Katsoulas, N.; Sapounas, A. A. (2006)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 ... -
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
Kittas, C.; Katsoulas, N.; Tsiropoulos, N.; Bartzanas, T.; Sapounas, A. A. (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 ...
