Flow disadvantage

Flow disadvantage is a disadvantage of the analyzed engineering system identified during flow analysis.

Overview

The flow disadvantages analyzed during the flow analysis can be divided into the following types:

Flow conductivity disadvantages can be the following:

bottleneck, i.e., a place in the flow channel where the resistance to flow is significantly increased (e.g., merging traffic lanes);
stagnant zone, i.e., a place where the flow stops temporarily or permanently (e.g., traffic red light);
poorly transferable flow (e.g., a speaking tube on a ship);
long flow (e.g., a power transmission line);
high channel resistance (e.g., 2-lane traffic compared to 4-lane traffic);
low flow density (e.g., transport of uncompressed mattresses);
large number of transformations in the useful flow (e.g., a traditional clock transmission).

Flow utilization disadvantages can be the following:

gray zone, i.e., a location in a flow where the parameters are difficult to predict (e.g., an icy road);
channel damages flow, i.e., a location in the channel where the channel damages the flow (e.g., a hole in the road surface);
flow damages channel, i.e., a location in the channel where the flow damages its channel (e.g., a pipe corroded by the flowing substance).
