Parallel and Counter Flow Designs Heat Exchangers .

A counter-flow heat exchanger is one in which the direction of the flow of one of the working fluids is opposite to the direction to the flow of the other fluid. In a parallel flow exchanger, both fluids in the heat exchanger flow in the same direction. Figure 9 represents the directions of fluid flow in the parallel and counter-flow exchangers. Under comparable conditions, more heat is transferred in a …

1.6 Co- versus counter-current flow - SW

The flows inside a heat exchanger can be arranged in various ways to fulfil different purposes. The possibilities are counter-current flow, co-current flow and cross-flow, the first two of which are shown in Figure 1.8.There are different forms of so-called cross-flow heat exchangers in which the flows are more or less mutually perpendicular.

Heat Exchanger - Real World Physics Proble

Note that a counterflow heat exchanger is more efficient than a parallel flow heat exchanger. It takes a smaller heat transfer surface area A s to achieve the same heat transfer rate q as a parallel flow heat exchanger, with all else being equal. But despite this there may be advantages to using a parallel flow heat exchanger instead of a ...

A cross flow heat exchange is one in which the two fluids are not in direct contact and flow roughly perpendicular to each other. These types are used typically when there is a phase change if one of the fluids. That fluid is almost always on the shell side. The most common example of a cross flow heat exchanger in a power plant is a condenser.
