Carrying Capacity of a Flow with Flow Rounding under Permafrost Conditions

  • Published:
Power Technology and Engineering Aims and scope

Under natural conditions in winter, narrowing of a flow due to partial freezing of the channel and formation of a slush ice run or ice jam, as a result of which flow speeds increase in sections of the turn of the channel, is characteristic. Laboratory experiments that have been carried out in the rotary installation of the hydraulics laboratory at the to model such a section, have shown that if the flow speeds entering the curvature increase or there is an increase in the Reynolds number, vortex motions and counterflows at the inner slope inevitably occur, which inevitably is shown in the nature of the channel washout.
