Atmospheric long-wave down-welling radiation is a fundamental element of climate change and of input to thermal simulation. Measuring long-wave radiation is needed to calculate locally total energy flows to the earth's surface and night cooling rates in urban precincts. It is an important...

In the present study, effects of hydrogen induction on combustion characteristics of a compression ignition diesel engine were investigated and a comprehensive model for identifying knocking combustion was developed. This was done by defining number of critical local regions within the CFD...

The energetic and exergetic performance of an updated ORC (organic Rankine cycle) is investigated. The thermal efficiencies of the ORC at different heat source temperatures of about 100, 90, 80, and 70 °C are explored. The thermodynamic irreversibility that takes place in the evaporator,...

The fundamentals of a newly constructed kW-scale Organic Rankine Cycle (ORC) system on the use of R123 were illustrated. A specially designed and manufactured turbine was innovatively applied to this system. Formulations were developed to examine the heat transfer and power conversion processes...

Improvements were made to a low-NOx axial swirl burner (LNASB), aimed at mitigating slagging in a 600-MWe boiler burning bituminous coal. The new design is referred to as improved low-NOx axial swirl burner (ILNASB). This paper describes investigations of the influence of swirl burner structure...

Domestic CHP (combined heat and power) generation is one new application of the ORC (organic Rankine cycle). An environment temperature fluctuation of 40 °C through the year is common in many areas, where the consumer's demand on heat follows a seasonal cycle. In no demand periods the ORC...

Recently some studies have been carried out on RCCI (reactivity controlled compression ignition) engines; however, they routinely used the “one factor at a time” approach, which may neglect interactions among the manipulated factors. This paper reports the use of a more effective approach...
