Abstract: (3245 Views)

In this research, first, a one-dimensional stable model for a catalytic stabilization reactor is presented. All mass transfer, heat transfer and momentum equations are considered in this model with applying appropriate assumptions. The results of modeling predict temperature and concentration changes and also pressure drop along the reactor bed length. By applying the modeling, hydrazine catalytic reactor was designed. The design procedure includes thrust and specific impulse and continues with calculation of the bed diameter. Ammonia dissociation is calculated regards to length of the bed and also mass flux. Finally, the reactor was designed and tested. In these tests, the maximum reactor temperature was 650 ^oC, the ammonia dissociation was 59% and the pressure drop was 1.3 bar, which presented a good fit with the modeling data.
