A novel laboratory pushing the limits for optics-based basic turbulence investigations

Developments in theoretical investigations and experimental techniques are reaching a level of maturity for which it is finally becoming possible to answer some the most pressing questions turbulence. The prevailing classical theories all have their strengths drawbacks based on respective principal assumptions. To better understand implications these assumptions, we developed theoryintensive strategy. For purposes, laboratory has been established at Department Mechanical Engineering, Technical University Denmark. objective being provide data necessary test (bounds of) validity existing theories; Most prominently Richardson-Kolmogorov-Batchelor paradigm, but also other generally adopted views such as Rapid Distortion Theory Equilibrium Similarity. measurements will be analyzed within novel framework that enables not only quantification degree small intermediate scale turbulence behaves according (and central assumptions), unveiling underlying processes create state turbulent flow. present work describe current developments building up laboratory.
