Understanding Unsteady Corner Separation Within Wing-Body Junction Flows
<p>Wing-body junction flows, formed at the interface between a wing and fuselage surface, are a complex, coupled, three-dimensional, turbulent flow field. This thesis focused on the unsteady corner separation that develops at the trailing edge of this wing-body junction under certain conditions. A …

Experimental Investigation of Turbulent Flows at Smooth and Rough Wall-Cylinder Junctions
Junction flows originate from the interaction between a fluid moving over a wall with an obstacle mounted on the same surface. Understanding the physics of such flows is of great interest to engineers responsible for the design of systems consisting of wall-body junctions. From aerodynamics to …

Wall Features of Wing-Body Junctions: Towards Noise Reduction
… have gone into studying idealized wing-body junction flows and their impact on horseshoe vortex and wake formation. The vortices have been found to generate regions of high surface pressure fluctuations and turbulence that are detrimental to structural components and acoustics. With the focus …

Assessment of RANS Turbulence Models for Strut-Wing Junctions
… validated for transonic, high Reynolds number, junction flows. This study intends to assess turbulence models by comparing drag and surface streamlines obtained from experiment and CFD. The test model is a NACA 0012 fin at Mach number of 0.75 and a Reynolds number of 6 million with varying angle …

Scour at the Base of Hydraulic Structures: Monitoring Instrumentation and Physical Investigations Over a Wide Range of Reynolds Numbers
Hydraulically induced scour of the streambed at the base of bridge piers is the leading cause of bridge failures. Despite the significant scientific efforts towards the solution of this challenging engineering problem, there are still no reliable tools for the prediction and mitigation of bridge …
