Department of aerogas dynamics and technical systems dynamics

Head of Department – Corresponding Member of the National Academy of Sciences of Ukraine, D.Sc., Professor V. I. Tymoshenko

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

1 — model conical entrance; 2 — high-pressure fan; 3 — feed pipe; 4 — suction pipe; 5 — flow regulator; 6 — inlet measuring header; 7 — U-tube gage

Assembly configuration of the bench

Full-scale model of the process apparatus flow system

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

1 — model spacecraft; 2 — model of a part of the spacecraft compartment; 3 — model of a part of the instrumentation module; 4 — perforated screen; 5 — heat-loss anemometer positioner; 6 —velocity pickup recorder;

Assembly configuration of the bench

Full-scale model of a part of the ∅2,500 mm spacecraft compartment of the Zenit-2 launch vehicle

3. Bench layout in the choice and tryout of a gas distributor for an ammonia conversion apparatus

1 — model apparatus casing; 2 — bearing cart; 3 — high-pressure fan; 4 — inlet measuring header; 5 — feed pipe; 6 — velocity pickup positioner; 7 — velocity pickup recorder (PC)
