The present study focuses on increasing the performance of a hydrocarbon-boron gel fuel ramjet. The research examines the option of condensing the combustion products, thus releasing the latent heat stored in the gaseous phase before they exit the engine and increasing the combustion efficiency. A two-step combustion process, using bypass air, was suggested to increase condensation. Three different models for the condensation of boron oxide were examined. The effect of bypass air injection on the condensation process was investigated, and the time required for complete condensation was estimated. The concentration of solid nuclei particles in the stream was found to have a major effect on the required time for the completion of boron oxide condensation; the more particles are present in the stream, the faster the condensation occurs.
