“…Similarly, it suggests that the flow rate and heat transfer coefficient are similar transversely. However, in wider plates, further manifold design considerations, like that presented by [33] will need to be implemented. …”

“…The rig was insulated with a custom-built Polyisocyanurate (PIR) box. The channels and manifolds were designed as a Z type heterogeneous ladder with two scale resistance; from the model presented by Tondeur, Fan, Commenge and Luo [33], the mal distribution in the channels is expected to be less than 20%. The absorber plate, shown in Figure 4, had sixty micro-channels 0.5 mm × 2 mm × 270 mm long spaced 1mm apart (3 mm pitch).…”

“…It is reported that a relatively uniform distribution may only be approached by making their hydraulic resistance much larger than that of the distributor and collector pipes if the latter have a uniform profile (e.g. Saber et al, 2009;Tondeur et al, 2011a). This usually implies that the distributor and collector pipes are large and encumbering, which is clearly unfavorable for miniaturized devices.…”

Parallel micro or mini-channels are widely used in various devices of process and energy engineering including microreactors, compact heat exchangers and fuel cells. Nevertheless, the flow maldistribution due to the improper design of distributor/collector is usually observed, leading to globally poor performances of these devices. The objective of this study is to optimize the shape of the distributor/collector pipes so as to achieve a uniform flow distribution among an array of parallel minichannels. A Z-type ladder fluid network with 10 mini-channels in parallel having square section is introduced and investigated. Two methods are used to optimize the shape of distributor/collector pipes: a discrete stairway shape optimized according to the scaling relations proposed by Tondeur et al. (2011) and a continuous tapered shape with the inclined angle varying from 0° to 30°. 3D-CFD simulations are carried out using the ANSYS FLUENT code. Numerical results obtained show that a relatively uniform flow distribution may be reached by the discrete stairway shape or by the linear tapered shape under very low flow-rate conditions. Larger inclined angle or fewer channels in parallel are favorable for more uniform flow distribution under higher flow-rate conditions. Nevertheless this implies that the distributor and the collector pipes occupy a large volume so that the entire device is less compact.
