Theoretical and Experimental Study of Phase Behavior of Carbon Dioxide as the Power Gas for Gas Guns

Popis výsledku v původním jazyce

The project is focused on the examination of the phase behavior of carbon dioxide (CO2) utilized as the source of energy for liquid propellant powered guns and further devices. Carbon dioxide can exist as a solid, liquid, gaseous or as a supercritical fluid depending upon the range of possible working conditions given by temperature and pressure. The one of objectives is to develop an equilibrium discharge and depressurization mathematical model for carbon dioxide tanks in order to assume thermodynamicequilibrium states at every point in time throughout draining under ambient conditions. In order to determine the critical flow, the speed of sound in a two-phase fluid is taken into consideration for the calculation algorithm. The developed model is solved by numerical integration with MATLAB using the explicit fourth-order Runge-Kutta method. An experimental setup was developed for the purpose of research and study of the phase behavior and state characteristics. In this project, a dev
