Abstract: Some features on the turbulent fronts were studied experimentally. The turbulence was produced by towing a grid with vertical square bars through a tank filled with linear stratified fluid. The shapes and behaviors of front motions were observed and recorded by shadowgraph and photograph. The data and paxameters of fronts were collected and computed by using an im age-digitized-microcomputer processing system from the traces of fronts.The variation of front pattern with time was examined. The front rapid co...
