1.6 Co- versus counter-current flow - SWEPThe 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 EXCHANGERS - ThermopediaIn a regenerative heat exchanger, the flow path normally consists of a matrix, which is heated when the hot fluid passes through it (this is known as the "hot blow"). This heat is then released to the cold fluid when this flows through the matrix (the "cold blow"). Regenerative Heat Exchangers are sometimes known as Capacitive Heat Exchangers ...

Mean Temperature Difference - Engineering ToolBoxMean Temperature Difference. The mean temperature difference in a heat transfer process depends on the direction of fluid flows involved in the process. The primary and secondary fluid in an heat exchanger process may. flow in the same direction - parallel flow or co-current flow; in the opposite direction - counter-current flow
Parallel vs. Counterflow Heat Exchangers for non-Engineers ...You can see that using linear flow, the most you can ever heat or cool to is the midpoint of the differential. That means that given an infinitely long heat exchanger and 0° and 100° fluids, the eventual temperature of both the hot and the cold will reach 50°. This is fairly efficient at first but quickly runs out of steam (pun intended).
