Description<\/strong><\/p>\n\n\n\n

The bench is an assemblage of one or more compressed air sources, a full-scale model of the flow system of the process apparatus under study with replaceable elements, and instrumentation for gas-dynamic parameter measurement, thus allowing one to model and effectively try out the flow system and operating conditions of the apparatus.<\/p>\n\n\n\n
