flow

a measurement of quantity over a specified period of time. Unlike a STOCK, which is not a function of time, a flow measures quantity passing per minute, hour, day or whatever. A common analogy is to a reservoir. The water entering and leaving the reservoir is a flow but the water actually in the reservoir at any one point in time is a stock. INCOME is a flow but WEALTH is a stock.

However, when the fully developed turbulent flow is disturbed by some obstacles, such as bends, then flow vortex and uneven particle concentration will form accordingly [27, 28, 39].

Steady-state, incompressible, turbulent flows are governed by the Reynolds-averaged continuity and Navier-Stokes equations.
For the case of channel, the fully developed turbulent flow bounded by two infinite, vertical, flat and parallel walls is simulated; the origin of the coordinate system is located at the channel wall and the x, y and z axes pointing in the stream wise, wall-normal and spanwise directions, respectively.
