The addition of proper-sized metal particles to the effervescent fuels increases the density of exhaust gases from rocket engines and the trust consequently. On the other hand, the addition of non-optimized metal particles causes combustion instability. Thus, the separation of proper-sized metal particles is under consideration here. In this study, among different methods of separating the aluminum particles in the fuel, the performance of the conic cyclone separator has been studied and the numerical results are validated by the experimental data. With a specific particle diameter and speed, the less the angle between the cyclone body and the horizon, the higher would be the separation efficiency. In addition, for increasing the separation efficiency of aluminum particle, it is recommended to build the inlet section of cyclone at the lower point of cyclone body.
