“…Jiao et al [10] investigated experimentally the effect of the inlet pipe diameter, the first header's diameter of equivalent area, and the second header's diameter of equivalent area on the flow maldistribution in plate-fin heat exchanger. Wen et al [11] investigated flow characteristics in the entrance region of plate-fin heat exchanger by means of particle image velocimetry (PIV). Tong et al [12] investigated numerically the strategies capable of perfecting manifold design to achieve the same rate of mass outflow through each of the exit ports of a distribution manifold.…”

The flow distribution in manifolds is highly dependent on inlet pressure, configuration, and total inlet flow to the manifold. The flow from a manifold has many applications and in various fields of engineering such as civil, mechanical, and chemical engineering. In this study, physical and numerical models were employed to study the uniformity of the flow distribution from manifold with various configurations. The physical model consists of main manifold with uniform longitudinal section having diameter of 10.16 cm (4 in), five laterals with diameter of 5.08 cm (2 in), and spacing of 22 cm. Different inlet flows were tested and the values of these flows are 500, 750, and 1000 L/min. A manifold with tapered longitudinal section having inlet diameters of 10.16 cm (4 in) and dead end diameter of 5.08 cm (2 in) with the same above later specifications and flow rates was tested for its uniformity too. The percentage of absolute mean deviation for manifold with uniform diameter was found to be 34% while its value for the manifold with nonuniform diameter was found to be 14%. This result confirms the efficiency of the nonuniform distribution of fluids.

“…The nonuniformity of flow field is detrimental to longitudinal wall conduction and the distribution of the interior temperature, which is the main reason that causes the deterioration of heat exchanger efficiency, especially for the compact heat exchanger [4,5]. It has been well recognized that the flow nonuniformity through the exchanger is generally associated with improper exchanger entrance configuration.…”

“…It has been well recognized that the flow nonuniformity through the exchanger is generally associated with improper exchanger entrance configuration. Therefore, most of previous studies mainly investigated the effects of different header configurations on the fluid flow distribution in PFHEs and tried to minimize the effect of flow maldistribution by optimizing the design of header configuration for PFHEs [4][5][6][7][8], with more attention paid to the optimization of industry-scale exchangers. Their large dimension of optimized distribution methods is not suitable for PFCCHE.…”
