摘要：Turbidity currents are helpful for regulating reservoir sedimentation.However,the movement of turbidity currents is affected by the water temperature in a stratified reservoir.It is necessary to analyze the motion of turbidity currents in stratified reservoirs.Flume experiments and a mathematical model were used to study the motion of turbidity currents in a stratified reservoir in this study.The phenomenon that turbidity currents traveled in different water layers was successfully demonstrated in flume experiments.Based on the RNG k-s turbulence model,we proposed a mathematical model that coupled the heat conduction and sediment transport equations.This model was verified by experimental data.This study confirmed that the interflow or overflow was different than the underflow in the reservoir when low sediment concentration turbidity currents entered the stratified water.The mathematical model established in this study was used to simulate the above phenomenon and was validated by experimental data.This study provides a calculation method for analyzing the turbidity currents entering a stratified reservoir.
