Abstract

A numerical analysis of the effects of focused energy deposition in the flow of a two-dimensional hypersonic nozzle at Mach 10 is presented. Computational Fluid Dynamics software modeling the full Navier-Stokes equations is used. Thrust, pressure, and temperature effects caused by the energy deposition inside the nozzle are shown. Increased quantities of energy deposited in the flow field create pressure distributions within the flow and along the nozzle boundaries that vary from the case in which no energy is deposited. The primary analysis focuses on the case where the maximum amount of energy is deposited into the flow while staying below the maximum temperature allowed by the simulation program. It is shown that thrust is considerably increased by the addition of focused energy to the flow. This energy deposition theory may lead to further improvements in the design of hypersonic nozzles to increase thrust and propulsion system efficiency and flexibility.
