Regarding the increased energy consumption of the processes at the operational units in the National Iranian Oil Company, the present study analyzed energy consumption at one of the gas refineries. In this refinery, which is the main supplier of Fajr Jam refinery for the national gas network, as well as an injection into the oil fields of the Iranian South oil company, the pressure of gas after...

The article investigates the effect of compressor pressure ratio, turbine inlet temperature and ambient temperature on the performance parameters of an air-cooled gas turbine cycle with evaporative cooling of inlet air. Air f ilm cooling has been adopted as the cooling technique for gas turbine blades. The mass of coolant required for turbine blade cooling is calculated f or a selected range of...

abstract due to low spatial resolution or simplifying of some micrometeorological phenomena, atmospheric general circulation models are not able to give a good estimation for weather conditions over study area. so their outputs should downscale into weather stations scales. in this research data of hadcm3 downscaled by using lars-wg5 with three scenarios, confirmed by ipcc including a1b, a2 and...

extended abstractintroductionsiberian high-pressure is one of the most important systems in climatology, which has been focused by all climatologists because of its influence area and expansion zone.unique features of this system including the expansion zone,the intensity of central pressure,which sometimes amounts to more than1075hp pressure at its core,its temperature and moisture characteris...

1n this program,aresearchgasturbinecombustor is used to study the influence of individual variables (in particular, fuel spray characteristics) on primary zone emissions. The unique combustor is operated under realistic conditions and allows for independent control of drop size, fuel-air ratio, air inlet temperature, pressure, reference velocity, and residence time. Also, it lends itself to the...
