Fundamentals of Fiber Optics for Multiphase Flows.

Fundamentals of Fiber Optics

1 Fundamentals of Optics

In this chapter, we discuss some of the fundamentals of optics. We first cover the electromagnetic (EM) spectrum, which shows that the visible spectrum occupies just a very narrow portion of the entire EM spectrum. We then discuss geometrical optics and wave optics. In geometrical optics, we formulate the propagation of light rays in terms of matrices, whereas in wave optics we formulate wave p...

Flatland optics: fundamentals.

"Flatland" is the title of a 120-year-old science fiction story. It describes the life of creatures living in a two-dimensional (2D) Flatland. A superior creature living in the three-dimensional (3D) spaceland, as we do, can easily inspect, for example, the inside of a Flatland house, as well as the content of a flat man's stomach without leaving any trace. Furthermore, the 3D person has supern...

A preconditioned solver for sharp resolution of multiphase flows at all Mach numbers

A preconditioned five-equation two-phase model coupled with an interface sharpening technique is introduced for simulation of a wide range of multiphase flows with both high and low Mach regimes. Harten-Lax-van Leer-Contact (HLLC) Riemann solver is implemented for solving the discretized equations while tangent of hyperbola for interface capturing (THINC) interface sharpening method is applied ...
