METHOD FOR VISUALIZATION OF GAS FLOW AROUND SURFACE

摘要

The invention relates to experimental gas dynamics, in particular to the methods for visualization of gas flows by means of visualization coatings. A method for the visualization of the pattern of gas flow around a surface includes application of visualization substance on the surface of the test object, this comprises a film-forming agent and filler observable under effect of electromagnetic radiation, this flows under effect of flow. The object is placed to gas flow and f the visualization pattern is registered. The method is improved by use of particles with cross dimension within (1-100)nm, for instance, carbon derivatives fullerenes (C) as filler, benzenes as film-forming agent, for instance, toluene. The technical result is in increase of reliability, self-descriptiveness and quality of experiment.
