Description
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.
1. Bench layout in the tryout of the inlet of a spouted-bed apparatus
Assembly configuration of the bench
2. Bench layout in the tryout of the design parameters of a ground thermostating system for the spacecraft compartment of the Zenit-2 launch vehicle
Assembly configuration of the bench
3. Bench layout in the choice and tryout of a gas distributor for an ammonia conversion apparatus
Assembly configuration of the bench
