Abstract:

Probes for pressure measurement in a pulse wind tunnels prechamber or in a ramjet combustion chamber are posed usually in face of a narrow duct adjoined to the tested volume. Therewith the pressure depends essentially on length of the used duct. At quick unsteady processes de pressure in long ducts is widely smeared in time and the pressure in short ducts has an oscillating character. At that a question on correspondence of a measured pressure to a real pressure in volume arises. This paper considers the problem for short ducts in the frames of the Euler equations.
