Abstract:
Ramjets have many applications and in the speed range of Mach numbers 2 to 5 show the best performance in terms of specific fuel consumption. In many applications, including some anti-air missiles, cannon and mortars, solid fuel ramjet can be used to improve the system performance.
In this thesis, two activities are performed:
A) One dimensional simulation of the internal flow field of solid fuel ramjet by development of available softwares.
B) Optimization of design parameters of a specific ramjet motor based on the above simulation.
The main target of this thesis is simulation of internal ballistics, design and optimization of a solid fuel ramjet for a particular application in the cannonball in order to increase the range. Beside the preliminary design of this engine, after the development of simulation software which includes the one dimensional simulation of diffuser flow field, flow field over the grain in the combustion chamber and nozzle flow field, the design is optimized using engineering methods and perspectives
