This book studies the dynamics of 2D objects moving through turbulent fluids. It examines the decay of turbulence over extended time scales, and compares the dynamics of non-spherical particles moving through still and turbulent fluids.
The book begins with an introduction to the project, its aims, and its relevance for industrial applications. It then discusses the movement of planar particles in quiescent fluid, and presents the numerous methodologies used to measure it. The book also presents a detailed analysis of the falling style of irregular particles, which makes it possible to estimate particle trajectory and wake morphology based on frontal geometry. In turn, the book provides the results of an analysis of physically constrained decaying turbulence in a laboratory setting. These results suggest that large-scale cut-off in numerical simulations can result in severe bias in the computed turbulent kinetic energy for long waiting times.
Combining the main text with a wealth of figures and sketches throughout, the book offers an accessible guide for all engineering students with a basic grasp of fluid mechanics, while the key findings will also be of interest to senior researchers.

About the author
Dr. Luis Blay Esteban is an Aerospace Engineer. After graduating from the Polytechnic University of Valencia, he was awarded an Aerospace M.Sc. from the Royal Society of Engineering under the bursary scheme, and moved to the University of Southampton to pursue an M.Sc. in Aerodynamics. Over the next three years, he completed his Ph.D. at the same university. The outcomes of research projects that he was involved with have been published in 7 articles in peer-reviewed journals and shared at more than 10 conferences/workshops.
