Abstract :
On the basis of analyzing the mechanism of coal–water paste (CWP) slip flow, the similitude criterion, known as general Reynolds number Reg which can characterize the state of non-Newtonian fluid flow in pipes, was put forward. The energy loss coefficient of CWP laminar flow has the same form as Newtonian fluid, i.e. λ=64/Reg. Reg holds good not only for the slip flow of non-Newtonian fluid, but also for slip-free flow as a steady-state laminar flow in pipes. The results obtained from experiments show that the energy loss coefficient of CWP laminar flow in pipes has the same form as Newtonian fluid.
