Studies on Flows Development in a Suddenly Expanded Circular Duct at Supersonic Mach Numbers

Abdul Aabid et al.

Summary: This article examines the flow development and static wall pressure distribution along the circular duct from the convergent-divergent nozzle. It found that oscillatory trends have a significant impact on the flow when jets are operated at higher NPRs. The control employed did not adversely affect the flow field and resulted in similar wall pressure magnitudes.

Determination of wall pressure flows at supersonic Mach numbers

Abdul Aabid et al.

Summary: This study investigates the wall pressure dissemination on a circular duct when the flow is exhausted into a CD nozzle, exploring the different pressure fluctuation trends under different Mach numbers and duct area ratios. The results show that the oscillations in the duct flow field disappear when the nozzles are ideally expanded.

Numerical investigation of splitter plate effect on bluff body using finite volume method

Azmil Afifi et al.

Summary: This study investigates the reduction of drag on a flat body by changing the length of the splitter plate. Results show that the splitter plate can be effective in reducing drag on bluff bodies. Simulation and validation using ANSYS Fluent suggest that the existing model is suitable for studying fluid flow.
