TL;DR: In this article , the design and analysis of an active impingement cooling system that can become the de facto choice for the hypersonic leading thermal protection system is presented. But, the authors consider a case in which the leading edge is exposed to a high heat flux due to an external Hypersonic Mach number of 7.

Density measurements using the Background Oriented Schlieren technique
TL;DR: In this paper, the authors describe the implementation of a novel technique called background-oriented Schlieren that can produce quantitative visualization of density in a flow using only a digital still camera, a structured background, and inverse tomographic algorithms which can extract two-dimensional slices from a three-dimensional sional flow.
Journal ArticleDOI
Computerized background-oriented schlieren
TL;DR: The BOS method offers not only the possibility of qualitative and quantitative schlieren investigations but also has the potential to determine density fields by integration of the measured gradient fields.

TL;DR: In this paper, a double free air jet was acquired using optical tomography and the projections of the density field were measured using the background oriented schlieren method (BOS).

On the applicability of background oriented optical tomography for large scale aerodynamic investigations
TL;DR: In this article, the density fields of the blade tip vortices from a helicopter in hover flight were visualized by a technique which does not require any installation on the helicopter or close to it.

Natural-background-oriented schlieren imaging
TL;DR: The background-oriented schlieren (BOS) flow visualization method has the potential for large-scale flow imaging outside the laboratory by using natural backgrounds instead of the artificial patterns normally used indoors.
