    • Flow characteristics and temperature patterns in a fan ventilated greenhouse 

      Fidaros, D.; Baxevanou, C.; Bartzanas, T.; Kittas, C. (2008)
      The effects of solar radiation distribution during fan ventilation in an arc type tunnel greenhouse in various hours of daylight were numerically investigated. Inside the greenhouse there was a tomato crop 1.5 m tall. For ...
    • IMPACT OF URBAN HEAT ISLAND DEVELOPMENT ON BUILDINGS' ENERGY CONSUMPTION 

      Papanastasiou, D. K.; Fidaros, D.; Bartzanas, T.; Kittas, C. (2013)
      The urban heat island (UHI) is one of the major problems that urban areas are experiencing worldwide, as it is related to various environmental and health effects. One of them is its direct impact on buildings energy demand. ...
    • Improving the efficiency of insect screens in greenhouses 

      Bartzanas, T.; Fidaros, D.; Baxevanou, C.; Katsoulas, N.; Kittas, C. (2009)
      A CFD code was used in order to study the influence of different types of insect screens on greenhouse microclimate and natural ventilation performance. The validity of the code was checked against experimental data. The ...
    • INFLUENCE OF HEATING SYSTEM ON GREENHOUSE MICROCLIMATE DISTRIBUTION 

      Tadj, N.; Bartzanas, T.; Fidaros, D.; Draoui, B.; Kittas, C. (2010)
      Convective and radiative heat transfer from heating systems significantly determines greenhouse microclimate during the cold period of the year. These mechanisms are complicated because they combine free and forced convection ...
    • Investigation of flow patterns in a greenhouse with mechanically assisted ventilation 

      Fidaros, D.; Baxevanou, C.; Bartzanas, T.; Kittas, C. (2011)
      In the present work, the effect of fan ventilation in an arc type tunnel greenhouse under the encumbering action of solar radiation is studied. Results are accrued for the air velocity, temperature, pressure, vapour and ...
    • Monitoring particulate matter levels and climate conditions in a Greek sheep and goat livestock building 

      Papanastasiou, D. K.; Fidaros, D.; Bartzanas, T.; Kittas, C. (2011)
      Atmospheric pollutants from livestock operations influence air quality inside livestock buildings and the air exhausted from them. The climate that prevails inside the building affects human and animal health and welfare, ...
    • Solar radiation distribution in a tunnel greenhouse 

      Baxevanou, C.; Bartzanas, T.; Fidaros, D.; Kittas, C. (2008)
      A commercial computational fluid dynamics code was used in order to investigate numerically the effect of solar radiation in an arc type tunnel greenhouse equipped with continuous side vents with a tomato crop. For the ...
    • Study of a passive solar heating greenhouse crop grow gutter 

      Katsoulas, N.; Kittas, C.; Fidaros, D.; Bartzanas, T.; Baxevanou, K. (2011)
      Water-filled transparent polyethylene tubes have been used as a passive solar system in greenhouses in Greece. In this work, the performance of a passive solar heating system used to serve as a crop grow gutter is studied. ...
