| description | There is growing interest in multi-nozzle array printing, as it has the potential to increase productivity and produce more intricate products. However, a key challenge is ensuring consistent flow across each outlet. In the heat exchangers, achieving uniform distribution of flow in parallel channels is a classic goal. To address this issue in multi-nozzle array direct printing technology, high-viscosity slurry fluids can be utilized in place of water, and the structure of compact parallel channels can be employed. This study experimentally and numerically investigated the flow distribution law of Herschel-Bulkley fluids (high-viscosity slurry fluids) entering each manifold of the compact parallel channels, which contained a single circular inlet and multiple outlets. The research identified two types of factors that impact the non-uniformity flow coefficient (<i>Φ</i>), which reflects the uniformity of flow distribution in each channel of the structure: entrance and exit conditions (<i>V</i>, <i>P</i><sub>1</sub>, <i>P</i><sub>2</sub>) that have a negligible effect on <i>Φ</i>, and structural dimensions (<i>D</i>, <i>S</i>, <i>L</i>, <i>N</i>, <i>A</i>, <i>d</i>) that are the primary influence factors. By analyzing the experimental results, a prediction model was derived that could accurately calculate <i>Φ</i> (error < 0.05) based on three structural dimensions: <i>A</i>, <i>S</i>, and <i>L</i>. Through proper design of these structural dimensions, a consistent flow rate of each channel of the parallel channels can be ensured. |
