Thermodynamic Limits of Work and Pressure Gain in Combustion and Evaporation Processes
Combustion and evaporation processes occurring in a closed chamber can result in significant pressure rise and direct work transfer. The pressure and volumetric changes that accompany such processes allow substantial work potential to be achieved in cyclic nonsteady devices, such as internal combustion engines and pulsed combustion or detonation engines. The ideal pressure gain or work producti...
متن کاملOptically accessible high-pressure combustion apparatus
The design and operation of a novel optically accessible high-pressure combustion apparatus is presented. The apparatus provides optical access for the direct observation of the morphology and development of premixed reaction fronts at elevated pressures. A chamber-in-chamber design with an innovative connecting system allows for safe, constant-pressure measurements, alleviating the extreme ove...
متن کاملEffect of High Injection Pressure on Mixture Formation, Burning Process and Combustion Characteristics in Diesel Combustion
The mixture formation prior to the ignition process plays as a key element in the diesel combustion. Parametric studies of mixture formation and ignition process in various injection parameter has received considerable attention in potential for reducing emissions. Purpose of this study is to clarify the effects of injection pressure on mixture formation and ignition especially during ignition ...
متن کاملInfant weight gain and later blood pressure.
To the Editor: Recently, Law et al1 reported that increased weight gain during early childhood (1 to 5 years) but not during infancy (birth to 1 year) is associated with later systolic blood pressure. From the latter, they concluded that “. . . none of the evidence so far indicates that promotion of infant growth increases cardiovascular risk.”1 In our opinion, this conclusion is not only incor...
متن کاملNegative radiation pressure on gain medium structures.
We demonstrate negative radiation pressure on gain medium structures, such that light amplification may cause a nanoscale body to be pulled toward a light source. Optically large gain medium structures, such as slabs and spheres, as well as deep subwavelength bodies, may experience this phenomenon. The threshold gain for radiation pressure reversal is obtained analytically for Rayleigh spheres,...
