Micro-chemical plants are chemical plants that use micrometrics structures by performing a numbering-up of microdevices. The flow distributor is responsible for the uniform distribution through these microdevices. Inadequate designs reduce the plant performance. Thus, 3D printing is a good alternative to allow fast and economic development for design tests. The present research applied 3D printing to manufacture flow distributors and evaluated the flow uniformity from experimental tests. This data article presents values of the non-uniformity flow coefficient (Ф) of three distinct distributors: the rectangular distributor (RD), the conical distributors with obstacle (CDO) and the conical distributor without obstacle (CD). The distributors were tested in water flow and at low flow rates, it was observed a flow maldistribution, related to the presence of air bubbles. For high flow rates the Ф reduced to values below 1%. The results presented here were used to validate the numerical simulations of flow distributors for numbering-up of biodiesel synthesis in micro and millidevices, "CFD analysis of flow distributor designs for numbering-up of biodiesel synthesis" [1].
微型化工厂是通过对微型设备进行叠加来使用微米级结构的化工厂。流量分配器负责使流体均匀地通过这些微型设备。设计不当会降低工厂性能。因此，3D打印是一种很好的选择，能够实现快速且经济的设计测试开发。本研究应用3D打印制造流量分配器，并通过实验测试评估了流量均匀性。这篇数据文章给出了三种不同分配器的流量不均匀系数（Ф）值：矩形分配器（RD）、带障碍物的锥形分配器（CDO）和不带障碍物的锥形分配器（CD）。这些分配器在水流中进行了测试，在低流速下，观察到了与气泡存在相关的流量分布不均现象。对于高流速，Ф降低到1%以下。这里给出的结果用于验证微型和毫微型设备中生物柴油合成叠加的流量分配器的数值模拟，“用于生物柴油合成叠加的流量分配器设计的CFD分析”[1]。
