استهسال انرژی ایجاد شده بر اثر ارتعاش ناشی از گردابه ها (vortex induced vibrations for aquatic clean energy) یا بطور مختصر vivace روشی نوین برای تولید انرژی پاک از جریان سیالات است.در این روش عبور جریان از اطراف یک استوانه باعث ایجاد ارتعاش شده و نیروی مورد نیاز برای حرکت دادن یک مولد الکتریکی را فراهم می آورد.
the aim of this paper is to assess the adaptation of iran’s energy policies to the kyoto protocol. in the past two decades, iran has experienced a considerable increase in greenhouse gas (ghg) emissions; in 2013 it was the world’s ninth largest emitter. although adapting to this protocol in iran’s energy and climate policies seems vital and urgent, its recent status is not promising. this paper...
An experiment with a 33 factorial arrangement in a completely randomized design with 450 day-old broilers was conducted to study the effect of energy level and time of change from starter to finisher diets on performance and economic aspects of broilers. Broiler chickens were fed at three levels of dietary energy (2800, 3000, and 3200 KcalME/Kg) from 1-42 days of age. Starter and finisher diet...
Significant energy is used to provide and maintain environmental conditions for thermal comfort in high-rise residential buildings, which largely depends on the components of the shell design. Therefore, to achieve high amounts of energy savings in buildings, high-impact design measures must first be defined and then optimized. This study seeks to answer the question of how the components of th...
The exposure of fruit surfaces to direct sunlight during the summer months can result in sunburn damage. Losses due to sunburn damage are a major economic problem when marketing fresh apples. The objective of this study was to develop and validate a model for simulating fruit surface temperature (FST) dynamics based on energy balance and measured weather data. A series of weather data (air temp...
