Summary of experimentally determined facts concerning the behavior of the boundary layer and performance of boundary layer measurements [PDF]
A summary report of boundary layer studies is presented. Preliminary results of experimental measurements show that: (1) A very thin layer (approximately 0.4 mm) of the boundary layer seems to be accelerated; (2) the static pressure of the outer flow ...

Realization of a spherical boundary by a layer of wave-guiding medium
, 2011 In this paper the concept of wave-guiding medium, previously introduced for planar structures, is defined for the spherically symmetric case. It is shown that a quarter-wavelength layer of such a medium serves as a transformer of boundary conditions ...

Unsteady transonic viscous-inviscid interaction using Euler and boundary-layer equations [PDF]
The Euler code is used extensively for computation of transonic unsteady aerodynamics. The boundary layer code solves the 3-D, compressible, unsteady, mean flow kinetic energy integral boundary layer equations in the direct mode.

High-Resolution Remote Sensing of the Gradient Richardson Number in a Megacity Boundary Layer
Remote SensingThe Gradient Richardson Number (Ri) is an important parameter for appraising the stability and turbulence exchange at the atmospheric boundary layer (ABL). However, high-resolution measurements of Ri profiles are rarely reported, especially in megacities.

Framing Failures in Wood-Frame Hip Roofs under Extreme Wind Loads
Frontiers in Built Environment, 2018 Wood-frame residential roof failures are among the most common and expensive types of wind damage. Hip roofs are commonly understood to be more resilient during extreme wind in relation to gable roofs.

Boundary layer thickness effect on boattail drag [PDF]
A combined experimental and analytical program was conducted to investigate the effects of boundary layer changes on the flow over high angle boattail nozzles. The tests were run on an isolated axisymmetric sting mounted model.

Generation of boundary and boundary-layer fitting grids [PDF]
The details of extended physical processes, such as the gas dynamic flow over an airfoil, the reactive flow through a combustor, or the electric field in a multi-contact transistor, are understood by solving the differential equations of a mathematical ...

Boundary layer relaminarization device [PDF]
Relamination of a boundary layer formed in supersonic flow over the leading edge of a swept airfoil is accomplished by means of at least one band, especially a quadrangular band, and most preferably a square band.
