High Reynolds Number Stratified Wake Studies

Abstract

Key questions on high Re near-field wake mixing, turbulence, structure (both velocity and density) will be addressed in the proposed effort, as well as the nature of the turbulence generated internal wave field. Studies of canonical bodies such as towed spheres provide a basis for understanding physical processes underlying wakes from realistic sources with more complex geometries through experimentation. This FY16-18 proposed effort is to build upon our prior grant, where properties of the early-time, high Reynolds number (Re) stratified wakes were measured in order to: (1) investigate the properties of the high-Re stratified turbulent wake of a towed sphere as a function of distance downstream, and (2) characterize the internal wavefield (IW) generated by the turbulent wake of a towed sphere under steady and non-steady (turning/accelerating) conditions.
