Film cooling technique has been successfully applied to gas turbine blades to prevent it from the hot flue gas. However, a continuous demand of increasing the turbine inlet temperature to raise the efficiency of the turbine requires continuous improvement in film cooling effectiveness. The concept of injecting mist (tiny water droplets) into the cooling fluid has been proven under laboratory co...

In this paper, using parabolic mirrors, a solar field was designed, which was related to a storage tank for a residential complex in the city of Tafresh located in the center of Iran. The design was performed for the existing oils: VP1, THERMINOL 66, THERMINOL 59. Finally, considering an organic cycle with R123 as working fluid and assuming a minimum length required for oil flow rate to reach a...

Courtyard geometry plays an important role in the amount of received solar radiation, also heating and cooling energy consumption of buildings. Considering this geometry for finding its proper proportion and orientation is significant to increase indoor thermal comfort, and as a result reduce the amount of energy consumption. This paper mainly focuses on a dormitory courtyard in Yazd and invest...

This study presents an optimal framework for the operation of integrated energy systems using demand response programs. The main goal of integrated energy systems is to optimally supply various demands using different energy carriers such as electricity, heating, and cooling. Considering the power market price, this work investigates the effects of multiple energy storage devices and demand res...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

Abstract Buildings account for 36% of global final energy demand and are key to mitigating climate change. Assessing the evolution building stock its is critical support mitigation strategies. However, most studies lack granularity overlook heterogeneity in sector, limiting evaluation transformation scenarios. We develop residential scenarios along shared socio-economic pathways (SSPs) 1–3 asse...

Air Conditioning (AC) appliances are a highly effective adaptation strategy to rising temperatures, thus making future climate conditions an important driver of space cooling energy demand. The main goal this study is assess the impacts change on Cooling Degree Days computed with wet-bulb temperature (CDDwb) and household demand in Brazil. We compare needs under three specific warming levels (S...

Ground source heat pumps (GSHPs) are one of the most widespread forms of geothermal energy technology. They utilise the near-constant temperature of the ground below the frost line to achieve energy-efficiencies two or three times that of conventional air-conditioners, consequently allowing a significant offset in electricity demand for space heating and cooling. Relatively mature GSHP markets ...
