Transition in boundary layer flows
An experimental investigation of transition in boundary layer flows under the influence of various freestream conditions is described.<br/><br/>Velocity profiles are obtained automatically by means of a stepper-motor driven traverse mechanism which carries a hot wire probe connected to a constant …

Fluid dynamics of boundary layer combustion
Reactive flows within a boundary layer, representing a marriage of thermal, fluid, and combustion sciences, have been studied for decades by the scientific community. However, the role of coherent structures within the three-dimensional flow field is largely untouched. In particular, little …

Integral Boundary Layer Methods in Python
… presents a modern approach to two Integral Boundary Layer methods implemented in the Python programming language. This work is based on two 2D boundary layer methods: Thwaites' method for laminar boundary layer flows and Head's method for turbulent boundary layer flows. Several novel …

High speed geological boundary layer flows
… following work is an investigation of high speed boundary layers in geological flows. In particular, it focuses on meteorite impact structures of the Martian double-layer ejecta (DLE) type and the Mount St. Helens eruption of 1980 which was hypothesized to be an underexpanded jet originally by …

Propulsion via buoyancy driven boundary layer
Heating a sloped surface generates a well-studied boundary layer flow, but the resulting surface forces have never been studied in propulsion applications. We built a triangular wedge to test this effect by mounting a resistive heating pad to one of its conducting sloped surfaces. We submerge the …

Boundary layer transport of small particles
… of small particles across the aerodynamic boundary layer that developed over a smooth, flat, acrylic plate and their subsequent deposition was investigated. The velocity boundary layer over the flat plate was characterized for a wind tunnel mainstream velocity of 2 m/s. Particle deposition …

Turbulent boundary layer models for acoustic analysis
An analysis of the three types of turbulent boundary layer (TBL) models for acoustic analysis is presented because current preferred models over-predict TBL contributions to aircraft interior noise predictions. The mean square pressure is a measure of the total energy due to the pressure …

Unsteadiness in shock-wave/boundary layer interactions
… observed in shock<br/>wave/turbulent boundary layer interactions has been driving research in this area for<br/>several decades. This work investigates the interaction between an impinging oblique<br/>shock and a supersonic turbulent boundary layer via large-eddy simulations. …

Boundary layer growth in a converging nozzle
A solution to the boundary layer equations for en incompressible fluid flow through a converging nozzle is presented. Calculations are based on a nozzle whose walls have a constant radius of curvature and a 2:1 entrance area to throat area ratio. An equation for the free stream velocity es a …

Large Eddy Simulation of Boundary Layer Combustion
… a preexisting numerical simulation solver from a boundary layer code to a code with variable mass density and combustion capabilities to produce high-fidelity simulations of turbulent non-premixed wall-flames. A series of verification studies have been developed using several benchmark laminar …

Boundary layer development from transition provoking devices
… variation in four representative transitional boundary layers is presented, the test cases encompassing free transition, transition due to a two-dimensional trip wire, with laminar and with turbulent re-attachment, and transition due to isolated spherical roughness elements.<br/><br/>The …
