Abstract
To investigate the relations between flow structure and velocity fluctuations in the vortex growth in bounded jet flow, the full Navier-Stokes equations with the primitive variables are solved by a finite difference method, and the process of vortex growth is visualized by marker particles. The vortex growth in. bounded jet flow can be distinctive. Firstly, to attract the feature, two-dimensional jet flows are investigated. Then, in comparison with the two-dimensional case the bounded jet flows are discussed. The vortex growth in a wall shear layer may be explained by same manner as in a free shear layer. From this point of view, three-dimensional vortex structure in the bounded jet flow can be explained.
