Study of Real Gas Behavior in a Single-Stage Gas Gun

Authors: A. Moradi, S. Khodadadiyan


In this paper, one-dimensional analysis of flow in a single-stage gas gun is conducted. The compressible inviscid flow equations are numerically solved by the second-order Roe TVD method, by using moving boundaries. For investigation of real gas effect the Noble-Able equation is applied. The numerical results are compared with the experimental data to validate the numerical scheme. The results show that with using the Noble-Able equation, the muzzle velocity decreases.

Keywords: ROE, projectile, Gas gun, muzzle velocity
