Abstract


Nowadays the increasing use of particle-laden flow in industries for various purposes requires studies in order to focus on reducing energy consumption in piping systems. The energy is consumed during the precipitation of particles at the bottom of the pipe and hence it needs higher energy to move it. In some studies, spiral pipe is considered one of the solutions to overcome the precipitation that occurs through the tangential force produced from the pipe geometry. Therefore, the purpose of this article is to investigate computationally tangential velocity of non-Newtonian flows through spiral pipes. The working fluid containing solid particles is called slurry, with concentration weight (Cw) of 30%. A spiral pipe with P/Di = 9 and variations ∆d has been used for the experiment. Further testing has been carried out using computational fluid dynamics using the RNG k–ɛ turbulent model. The simulation results have a good agreement with the experimental ones.
