CFD simulation of heating greenhouse using a perforated polyethylene ducts
(2017)The location and the power of the heating devices determines in a large extend the flow and temperature patterns inside the greenhouse. The aim of this paper is to analyse the internal convective flows generated in a closed ... -
Characterization and analysis of the effects of greenhouse climate control equipment on greenhouse microclimate and crop response
(2011)An overview of the recent scientific and technical advances on issues concerning the greenhouse microclimate, control and management in Mediterranean regions is presented and discussed. Special emphasis is given on the ... -
Daily temperature optimisation in greenhouse by reinforcement learning
(2005)The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously ... -
Dynamic modelling of an ultra high temperature PCM with combined heat and electricity production for application at residential buildings
(2020)The present study investigates the thermal performance of an ultra-high temperature (> 1000 °C) latent heat thermal energy storage system that utilizes silicon as a phase-change (PCM) material. Application of this system ... -
The effect of microwave operation parameters on the electrochemical performance of Pt/C catalysts
(2011)In the present work, the effect of the microwave operation parameters on the heating behaviour of ethylene glycol (EG) solution and thereafter on the physicochemical and electrochemical properties of Pt/C catalysts have ... -
Energy needs and energy saving in Mediterranean greenhouses
(2014)A fully-automated and climate-controlled greenhouse requires heating, ventilation, cooling, dehumidification and shading systems to control the microclimate conditions and create an optimal environment for crop growth and ... -
Energy performance optimization of a house with grid-connected rooftop pv installation and air source heat pump
(2021)The use of air source heat pump systems for space heating and cooling is a convenient retrofitting strategy for reducing building energy costs. This can be combined with the rooftop installation of photovoltaic panels, ... -
Heating and cooling induced stresses and displacements in heat exchanger piles in sand
(2020)Heating and cooling of heat exchanger piles causes changes in the axial stresses in the pile and vertical pile displacements. Changes in axial stress (thermal stresses) are more significant in the case of fixed head piles, ... -
Multiplying magnetic hyperthermia response by nanoparticle assembling
(2014)The oriented attachment of magnetic nanoparticles is recognized as an important pathway in the magnetic-hyperthermia cancer treatment roadmap, thus, understanding the physical origin of their enhanced heating properties ... -
Numerical and experimental analysis of convective heat transfer in a heated greenhouse
(2008)Internal convective flows, resulted from buoyancy forces, in a greenhouse tunnel were numerically and experimentally analysed and discussed. Experiments were performed in an experimental arc type tunnel greenhouse with a ... -
Numerical study of mechanically ventilated broiler house equipped with evaporative pads
(2018)One of the important factors to improve the broiler production is the provision of an optimum indoor environment (air quality, temperature, humidity, air velocity, gases and PMs concentration) with lower possible cost. The ... -
“On-Line” Heating Emissions Based on WRF Meteorology— Application and Evaluation of a Modeling System over Greece
(2022)The main objective of the present study is the development of an “on-line” heating emissions modeling system based on simulated meteorological data and its integration with air quality modeling systems in order to improve ... -
Preliminary findings on seasonal heat stress of sheep
(2012)This paper studies the heat stress conditions imposed onto sheep housed in a naturally ventilated sheep barn during the four seasons of a year. The barn is located near the east coast of central Greece. Heat stress is ... -
Technological properties and fire performance of medium density fibreboard (MDF) treated with selected polyphosphate-based fire retardants
(2020)The objective of the work was to evaluate the efficacy of two new polyphosphate-based fire retardants (FRs) and one commercial product named Siriono® on the fire performance and physical–mechanical properties of medium ... -
Thermal buckling behaviour of unstiffened and stiffened fixed-roof tanks under non-uniform heating
(2018)The problem addressed in this paper is the thermal buckling behaviour of thin-walled steel cylindrical fixed-roof tanks under non-uniform loading, induced by an adjacent tank. This specific type of thermal loading can be ...
