Aeroacoustics and Artificial Neural Network Modeling of Airborne Acoustic Emissions During High Kinetic Energy Thermal Spraying
(2019)This work describes an online, non-destructive monitoring technology for thermal spray coating processes based on the airborne acoustic emissions (AAE) in the booth. First, numerical simulations were carried out to probe ... -
Analysis of the dynamic air conditioning loads, fuel consumption and emissions of heavy-duty trucks with different glazing and paint optical properties
(2022)The European transportation sector employs 10 million people and accounts for 4.6% of the European Union GDP. Due to climate change, this workforce is increasingly affected by high temperatures and radiant loads, particularly ... -
Harvesting of cotton residue for energy production
(1999)The possibility of collecting cotton stalks in Greece and using them for energy production was investigated. The production and properties of cotton stalks were studied and a system for collection of the aerial part is ... -
Importance of measuring tillage implement forces for reduced fuel consumption and increased efficiency without affecting tillage depth
(2015)Tillage and especially ploughing is the most energy and cost demanding field operation. The cost of tillage operations in arable farming sometimes exceeds 50% of the total fuel costs for completing all field operations ... -
Isolation of soil bacteria able to hydrolyze both organophosphate and carbamate pesticides
(2011)Two bacteria identified as Pseudomonas putida and Acinetobacter rhizosphaerae able to rapidly degrade the organophosphate (OP) fenamiphos (FEN) were isolated. Denaturating gradient gel electrophoresis analysis revealed ... -
Potential growth and biomass productivity of Miscanthus x giganteus as affected by plant density and N-fertilization in central Greece
(2007)The potential growth and biomass productivity of Miscanthus x giganteus was investigated under constraint-free conditions during two years with appreciable different climatic conditions in central Greece, and under three ... -
A simple model for breakup time prediction of water-heavy fuel oil emulsion droplets
(2021)Immiscible heavy fuel-water (W/HFO) emulsion droplets inside combustion chambers are subjected to explosive boiling and fragmentation due to the different boiling point between the water and the surrounding host fuel. These ... -
Sustainable solutions for reducing air-conditioning costs and tailpipe emissions from heavy-duty transportation across Europe
(2022)Heavy-duty trucks emit >25% of the CO2 of the European road transport sector despite representing ≈2.5% of its fleet. Escalating temperatures associated to global warming will increase the use of air-conditioning (AC) ... -
Switchgrass (Panicum virgatum L.) nutrients use efficiency and uptake characteristics, and biomass yield for solid biofuel production under Mediterranean conditions
(2014)Switchgrass produces high amounts of biomass that can be used for solid biofuel production. In this study, the dry biomass yield vs. N-P-K nutrient uptake relations as well as the N-mineralization and the N-fertilization ... -
Techno-economic assessment of gas turbine cogeneration cycles utilizing anaerobic digestion products for biogas fuel
(2017)This work presents the development of an integrated approach for the techno-economic assessment of recuperated gas turbine cycles utilizing anaerobic digestion (AD) products of animal manure and energy crops for biogas ...
