in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...

The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...

Ambitious targets for reducing carbon dioxide (CO2) emissions are set by Norwegian authorities to address the concerns about global warming. Emission reductions in offshore heat and power sector can play a role reaching these targets. Parts of efforts industry academia reduce concerned with introducing new design configurations or proposing novel operational strategies combined cycles. Therefor...

Despite the higher efficiency advantage, cost reduction of PV technology has been more successful compared to dish Stirling engine (DSE) due large market volume and sturdy competition. Irrespective types source, there exists a potential waste heat recovery from engines operating at temperature regime. Accordingly, make DSE commercially viable efficient, innovative ways such as hybridization (co...

To determine the amount of air pollutants, produced by Iranian automakers, and compare it with old and retrofitted vehicles have become one of the important tools of urban management. The present research uses International Vehicle Emission (IVE) modeling software in order to verify SAIPA Co. fleet emissions, based on Euro 4 emission standard (SAIPA Co. recognized as a superior Iranian brand in...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...
