The Buoyant Jets were analysed experimentally changing flow rate (0.0291/s, 0.0371/s, 0.0451/s), ratio of nozzle tip area to throat area (aspect ratio β=0.4, 1.0, 1.9), and also the temperature difference (△T=Ti - T∞) between the temperature of the inflow water into the storage tank (1 mx 1 mx 3m) and the mean temperature of the water in the storage tank were changed as 25℃, 35℃ and 45℃.
The more aspect ratio decreased, the more the trajectories of Buoyant Jets centerline were decreased and not the more the trajectories of Buoyant Jets centerline were influnced by the increment of the difference of the temperature.
The more aspect ratio decreased, the more the half widths and dilution ratio of Buoyant Jets were increased and not the more the half widths and dilution ratio of Buouant Jets were influnced by the increment of the difference of the temperature.
Fr number is the factor that can predict the flow pattern over the whole flow field. And yet for the consideration the near field of Buoyant Jets flow pattern is dominated by magnitude of momentum and buoyancy force.
