Piping/Fluid Flow

Minimize power consumption in slurry transport

Accurately predict critical velocity

Ghanta, K. C., Lahiri, S. K., National Institute of Technology

Transporting slurries through pipeline is common in the solids handling, mineral and hydrocarbon processing industries because use of a pipeline ensures a dust-free environment, requires substantially less space, makes full automation possible and requires less operating staff. On the other hand, it needs higher operating pressures and considerable demands for high-quality pumping equipment and control systems. Due to intense global competition, the process industries are forced to reduce the power consumption of slurry transport to remain competitive in the world market. This article develops a numerical technique to minimize power consumption of slurry transport in long pipelines by predic
