| Summary: | Application of Computational Fluid Dynamics (CFD) in studying solid propellant
rocket motor have been growing steadily. This is due to the fact that experimental
work will cost more time and money. Other than that, the industry needs more
understanding to guide designer for more reliable technical solution and less
expensive in order to design solid rocket motor for missiles and space launchers.
To bring new knowledge for solid rocket propulsion, CFD has been important
and dependable. However, to validate the dedicated models and numerical
simulation, experimental procedure was important. For the design process, solid
propellant rocket with medium thrust produced been focused in the current work.
The works are including experimental and CFD simulation approaches. For the
experimental work, the static firing test will be used. As for the fabrication of the
propellant grain, it been conducted at the authorized centre by the Malaysian
authority. Meanwhile for the CFD simulation, the work will be focus on the
internal flow inside the nozzle. The findings show that data has significant errors
due to the failure of the SRM bulkhead during experimental analysis. Due to the
Covid 19 pandemic, the experimental work cannot be repeated and therefore
was presented as it was. Next findings show the normal nozzle with different
throat length simulation. It was found that the throat length has significant impact
on the performance of the nozzle flow. Finally, findings from parametric study
about the dual bell nozzle. The results show that the dual bell nozzle can
increase the effectiveness of the nozzle flow. In overall, the work has covered all
the intended objectives and CFD analysis has been prove as useful design tools
used to lessen the amount of physical testing that must be done to validate a
design and measure its performance. |
