Abstract

Many interesting and important basic problems still remain unsolved or ever untouched in the fields of experimental fluid dynamics. The present report explains a variety of newest results of wind tunnel experiments conducted chiefly in our laboratory with respect to the features of large scale quasi-isotropic turbulence, anisotropic turbulence, three-dimensional vortical structure in the wake of a sphere, the process of vortex pairing in a two-dimensional jet, the proposal for a new model on a boundary layer transition in a view point of hairpin or horse-shoe vortex and lastly the analysis on spontaneously generated internal gravity waves in a stably stratified mixing layer. These results, the author guesses, will promise the future possibility in the fields of experimental fluid dynamics.
