The primary purpose of this research is to investigate the effectiveness of rib as a passive control to control the flow development around the circular duct at different levels of expansion using Computational Fluid Dynamics (CFD). The nozzle pressure ratio (NPR), rib size, and rib orientation were considered in this research. The L/D ratio is 3 t
Requirement engineering (RE) helps to effectively define users’ needs and produce quality set of requirements. Nonetheless, RE efforts consume a lot of resources due to many contributing and challenging factors. Requirement reuse using pattern can help to reduce the RE resources. This work investigates requirements reuse using pattern by applying
