Basic Hydrodynamics

Abstract

Basic hydrodynamic studies in turbomachinery and hydrodynamic drag reduction have been conducted. In the turbomachinery thrust area, the overall objective is to develop an improved understanding of the complex three- dimensional flows typical of incompressible rotor and stator flows; this effort has been primarily computational in nature. The second thrust area is axisymmetric turbulent flow drag reduction through microbubble injections. The third thrust area objective is to assess experimentally the effects of wall suction of turbulent boundary layer skin friction with possible applications to drag reduction. A fourth thrust area was a combined analytical and experimental study on laminar boundary layer/particle interaction physics.
