PULSED AIR HEATER Russian patent published in 2011 - IPC G01M9/00 

FIELD: physics.

SUBSTANCE: proposed device may be incorporated with pulsed compressed gas heaters intended for simulation and analysis on jet flows in vacuum chambers at 10-30 MPa to heat compressed has to 500-600 K and higher. It comprises low- and high-pressure chambers connected in series and provided with fast-operation shut-off devices at their outlets. In compliance with this invention low-pressure chamber is furnished with two perforated diaphragms, one arranged at chamber inlet and another at distance from its outlet equal to or smaller than one third of chamber length. Note also that perforations diameter is selected subject to relation: 0.3≤d*≤0.75, where d*=d/d_c, d is perforations diameter, and d_c is low-pressure chamber diameter.

EFFECT: higher reliability, simplified process and design.
