Parallel Flow

parallel flow

[′par·ə‚lel ′flō]
(electricity)
Also known as loop flow.
The flow of electric current from one point to another in an electric network over multiple paths, in accordance with Kirchhoff's laws.
In particular, the flow of electric current through electric power systems over paths other than the contractual path.

Parallel Flow

 

a pattern of movement of working liquids or gases in a heat exchanger whereby fluids divided by a wall flow in identical directions; the heat transfer occurs through the wall. With parallel flow the average temperature difference between the working liquids is substantially less than with counterflow, especially if the temperature difference at the outlet side is small. However, in a number of cases this pattern makes it possible to obtain lower wall temperatures than are obtained with counterflow.

When a single-phase fluid flowing continuously at steady state is split into N parallel flow paths, which then recombine at a common destination, as illustrated schematically in Figure 1, the requirement that the pressure drop be identical through each of the paths results in a uniform distribution of the fluid, i.e., we expect a fraction of (1/N) to pass through each of the separate channels.
