As a result of their unique heat recovery properties, Humidified Gas Turbine (HGT) cycles have the potential to deliver resource-effective energy to society. The Evaporative Gas Turbine (EvGT) Consortium in Sweden has been studying these types of cycles for nearly a decade, but now stands at a crossroads, with commercial demonstration remaining. This thesis binds together several key elements f...

An optimization tool for offshore bottoming cycle and heat recovery steam generator (HRSG) design has previously been developed. The is based on empirical correlations to obtain hydraulic thermal quantities the HRSG. However, as these are experiments with typical onshore designs, they may not be valid compact designs encountered in HRSGs.In order extend validity range of tool, this work present...

Air pollution can influence women's reproductive health, specifically menstrual cycle characteristics, oocyte quality, and risk of miscarriage. The aim of the study was to assess whether air pollution can affect the length of the overall menstrual cycle and the length of its phases (follicular and luteal). Municipal ecological monitoring data was used to assess the air pollution exposure during...

the centralization of human activities is associated with different pollutants which enter into environment easily and cause the urban environment more vulnerable. regarding the importance of air pollution issue for tehran metropolis, many plans and regulations have been developed. however, most of them failed to decline the pollution. the purpose of this study was to pathologically analyze air...

Concerning the use of HFCs as substitutes for CFCs and HCFCs a major concern in applications with remarkable leakages of refrigerant is its contribution to global warming. Therefore, the attention has been drawn to the use of natural working fluids, like carbon dioxide, hydrocarbons, water and air. Air had been already used in the range of air conditioning technology. Air as refrigerants is sta...

In this study, energy assessment is performed for an industrial turbocharged diesel engine integrated with a novel waste heat recovery (WHR) system. The exhaust used in inverted Brayton cycle (IBC) purpose. Also, the from IBC exchanger as source organic Rankine (ORC) to produce extra power. case study modelled AVL BOOST software and model validated against real performance data. For studying of...

In this paper, exergy and exergoeconomic analysis is performed on the recently proposed process forthe coproduction of liquefied natural gas (LNG) and natural gas liquids (NGL) based on the mixedfluid cascade (MFC) refrigeration systems, as one of the most important and popular natural gasliquefaction processes. To carry out this analysis, at first, the proposed process is sim...

In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...

Air temperatures were continuously recorded inside four incubators with proportional heating control and six incubators with on/off heating cycles, during routine use. The air temperatures in the former were constant throughout, with a gradient between the roof and above-mattress air temperature not exceeding 1 degree C. In contrast, the recordings from the latter models showed a regular cyclic...

Despite advances in surgical techniques and breast implant design, certain problems unique to breast implant surgery remain. The historically most onerous problem, capsular contracture, is relatively uncommon now. However, problems related to thin capsules and periprosthetic atrophy are becoming more common; these problems include rippling, symmastia, implant malposition, and bottoming out. Opt...
