Supersonic flow of gases in pulsed molecular beam

Abstract EN

In this work the acceleration of gases in pulsed molecular beam system was studied.

The relation between the stagnation pressure and gas velocity was presented.

Also the relations between these values of velocities and the values of temperature corresponding to them were studied.

The high value of gas velocity was obtained when we used the mixture of gas consist of (0.05 Sf6 + 0.95Ar) with stagnation pressure equals to 1.6 bar.

This value of velocity reached up to 4.48 Mach and which corresponds to temperature degree approaches to 33.4 ◦K.
