The aim in this chapter is to investigate the multidimensional Lamb equation, which interconnects a covector field u(x, t), a vector field v(x, t), and a function h(x, t): $$ frac{{\partial u}}{{\partial t}} + ({\text{rot }}u)v = - \frac{{\partial h}}{{\partial x}}. $$ (1.1)

Effects of Vortex-Vortex Interaction in a Compressor Cascade With Vortex Generators
Volume 2A: Turbomachinery, 2015This paper presents a numerical investigation to explore the effects of vortex generators on a high speed compressor cascade. Secondary flow effects like the corner separation vortex have an influence on the performance of a compressor cascade such as leading to increased losses.

Devil’s vortex-lens arrays generating 3D optical vortex structures
SPIE Proceedings, 2013Optical vortices are employed in optical trapping applications for their ability to set microparticles into rotation. Devil’s Vortex Lenses have high diffraction efficiency and it is possible to take advantage of their particular volumetric focal structure to design versatile and efficient optical tweezers.

Tip vortex cavitation control by the micro vortex generator
Physics of FluidsThe present study investigates the control effect of a vane-shaped micro vortex generator (VG) on the inception and development of tip vortex cavitation. Five different arrangements were tested by varying the position and installation angle near the tip of a NACA (National Advisory Committee for Aeronautics) 662-415 hydrofoil.
