Abstrakt
The most common direction of increasing power and reducing fuel consumption is contact cooling of the air flow by water injection.
The methods of cooling cycle air include technology of thermogasdynamic compression – an increase in pressure as a result of the instantaneous evaporation of injected liquid into the airflow accelerated to the speed of sound in a two-phase jet device – aerothermopressor.
An analysis of a number of models was carried out using computer CFD-modeling to determine the main characteristics of the aerothermopressor.
As a result of thermogasdynamic compression, the increase in the air pressure of the aerothermopressor has been 1.5–10.0% at incomplete evaporation.
It was found that provides efficient fine atomization of a liquid with an average droplet diameter of 20μm. This contributed to an isothermal process in the compressor. It allowed to increase efficiency and to reduce specific fuel consumption by 1.5-2.0%.
