Experimental pressure drop results on boiling water flow through three helical coils of tube inner diameter of 4.03 mm and 4.98 mm and coil diameter to tube diameter ratio of 26.1, 64.1 and 93.3 are presented. Both subcooled and saturated flow boiling are ...
Wave breaking and wave runup/rundown have a major influence on nearshore hydrodynamics, morphodynamics and beach evolution. In the case of wave breaking, there is significant mixing of air and water at the wave crest, along with relatively high kinetic ene ...
The Swiss Federal Office of Energy has published directives in order to limit the increase of electrical energy consumption to a maximum of 5% in 2010 in comparison with 2000. To reach this goal, clear measures have to be taken regarding the installation a ...
Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...
Around 3/4 of global resources are currently consumed in urban settlements, with corresponding adverse environmental consequences. According to population forecasts this situation will worsen in the coming years. It is therefore imperative that we understa ...
Thermal comfort depends on heat exchanges of the body by conduction evapo-transpiration and convection to the air, and radiation to and from surrounding surfaces. Usual ways of sizing heating and cooling systems are based on homogeneous temperature in the ...
Decentralized energy systems are thought to have great potential for supplying electricity, cooling, and heating to buildings. A decentralized system combining a solid oxide fuel cell (SOFC) with an absorption chiller- heater (ACH) is proposed. The CO2-emi ...
In order to extend the application range of air-water heat pumps to high temperature residential heating systems, new small hermetic compressors with remodeled injection ports for vapor injection have successfully been tested in laboratory. The injection f ...
Methods to measure airflow rates using tracer gas in single air handling units are well known. In some buildings however, in particular in Singapore, rooms are often ventilated with two or more units and present large recirculation rates. Large recirculati ...
