内容記述 | The axisymmetric plums and the axisymmetric jets are investigated analytically. The k-\epsilon\ turbulence model is adopted in the analysis. Both axisymmetric plumes and jests satisfy the similarity solutions, which are independent on the Reynolds number and the Richardson number. Therefore the similarity Solutions are expected to be applicable to the wide range of hydraulic conditions. The velocity distributions of the plume and the jet obtained herein explain well the experimental results. The distributions of relative density difference predicted for the plume also show a good agreement with the experimental data. The value of the turbulent Schmidt number \sigma\_t_= 0.4 for the axisymmetric plumes is, however, somewhat smaller than the values of \sigma\_t_= 0.8-1.0 for the inclined wall plumes and for the plane plumes. | |||||
