Simulation of pipeline transport backfill mixtures

The paper is focused on description of the created simulator pipeline transport of backfill mixtures. Pipeline transport is one of the most important process of backfilling with paste mixtures. The composition of the backfill mixtures should take into account its influence on the final strength and transportability. The proposed simulator allows calculations of pipeline transport´s output parameters (necessary parameters of pumps, energy intensity of transport and parameters for mixture flow - Reynolds and Freuds number of flow, the flow velocity, critical velocity, friction coefficient, height loss ...) based on the input parameters defining the composition of the backfill mixture and the conditions of transport. This helps to find the optimal composition of the backfill mixture for the requirements of its applications and transport.
