Cycling loading effect on a solid propellant engine performances part 3: overview over the 2D and 3D CFD studies versus experimental results

The article will summarize few of the achievements after the experimental and computational research on both 2 D axis symmetric and 3 D axis symmetric CFD modeling of the flow inside a solid propellant rocket engine with a specific axial distribution of the propellant's material temperature generated by the long run flight vibrations. The solid propellant was assumed to be a vascoelastic material under cycling loading. The 2D and 3D modeling results of the rocket engine's internal flow parameters and performances will be evaluated and compared with few of the performed experimental results.
