Another example is a wall with a dissimilar material such as a bolt in an insulating layer. In this case, the heat transfer resistances are in parallel. Figure 16.7 shows the physical configuration, the heat transfer paths and the thermal resistance circuit. (16.. 23)
Parallel and Counter Flow Designs Heat Exchangers - Engineers Edge
The design of a parallel flow heat exchanger is advantageous when two fluids are required to be brought to nearly the same temperature. The counter-flow heat exchanger has three significant advantages over the parallel flow design.

In the parallel-flow arrangement of Figure 18.8(a), the hot and cold fluids enter at the same end, flow in the same direction, and leave at the same end. In the counterflow arrangement of Figure 18.8(b) , the fluids enter at opposite ends, flow in opposite directions, and leave at opposite ends.
temperatures and the heat transfer rate for a heating coil in which air is heated using hot water with two passes. The overall heat transfer conductance is 4 kW/C. The air stream enters at 24 C with a flow rate of 3 kg/s, and the water stream enters at 60 C with a flow rate of 1.0 kg/s.
Parallel Flow - (Heat and Mass Transfer) - Vocab, Definition
Parallel flow is a configuration in heat exchangers where the hot and cold fluids move in the same direction, entering at the same end and exiting at the opposite end. This arrangement affects the temperature change of both fluids and influences the efficiency of heat transfer.
Difference Between Parallel Flow, Counter Flow, and Crossflow Heat …
Apr 30, 2024 · To help you better understand parallel flow vs. counter flow vs. crossflow patterns, we’ll go into more detail on each option. A parallel flow pattern, also referred to as a cocurrent flow, is one in which the shellside and tubeside fluids flow in the same direction.
Heat Exchangers - Engineering Library
Whether parallel or counter-flow, heat transfer within the heat exchanger involves both conduction and convection. One fluid (hot) convectively transfers heat to the tube wall where conduction takes place across the tube to the opposite wall.
Parallel-flow heat exchanger - Vocab, Definition, and Must
A parallel-flow heat exchanger is a type of heat exchanger where both the hot and cold fluids move in the same direction, allowing for heat transfer between them as they flow side by side.
Heat Exchanger Flow: Cross flow, Parallel flow, Counter Flow Heat ...
The Parallel Flow Heat Exchanger. A double pipe heat exchanger can be operated in parallel flow mode as shown in the diagram at the left. Similarly a shell and tube heat exchanger can be operated in approximately parallel flow by having both …
Heat Exchanger Configurations | Parallel Flow & Counterflow
Dec 20, 2024 · Many fluid-to-fluid heat exchanger calculations can be couched in terms described by the easy-to-visualize cases represented by counterflow and parallel flow concentric pipe heat exchangers. In these two flow configurations, one fluid flows through a central pipe, while the other flows in the annulus between the central pipe and a larger pipe.
