Estimation of Ozone Trend in Central Greece, Based on Meteorologically Adjusted Time Series
(2012)
Data referring to an approximately 8-year period (1999-2007) are analyzed in order to estimate the trend of the daily maximum hourly value of ozone concentration at the east coast of central Greece, where the summer ...
Temperature, comfort and pollution levels during heat waves and the role of sea breeze
(2010)
During the summer of 2007 several Greek regions suffered periods of extreme heat, with midday temperatures of over 40A degrees C on several consecutive days. High temperatures were also recorded on the east coast of central ...
IMPACT OF URBAN HEAT ISLAND DEVELOPMENT ON BUILDINGS' ENERGY CONSUMPTION
(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. ...
Development of models to assess potential sheep heat-stress during heat waves
(2013)
It is well documented that heat-stress burdens sheep welfare and productivity. It is expected that peak heat-stress levels are observed when high temperatures prevail, i.e. during heat waves. However, continuous measurements ...
Improvement of greenhouse microclimate distribution by means of air mixing fans
(2012)
The objective of this work was to experimentally investigate the influence of air mixing fans on air temperature and humidity distribution in an arched roof greenhouse. The greenhouse was occupied by a tomato crop and ...
Microclimate of a pepper crop under screenhouse conditions
(2012)
In the present study, the influence of three different shading nets with different colour, shading intensity and porosity on the screenhouse and crop microclimate was experimentally investigated. The experiments were carried ...
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 ...
Experimental results and spatial simulation of climate in a greenhouse with insect screens
(2011)
Aim of the present paper was to present, analyze and compare detailed experimental data and CFD simulation results in a greenhouse equipped with insect screens. The studied greenhouse was a round arch type with vertical ...
Solar radiation distribution in screenhouses: A CFD approach
(2012)
In this paper the effect of solar radiation distribution in a typical screenhouse was numerically investigated, taking into account the thickness and aerodynamic properties of the screen and its spectral, optical and thermal ...
