基于微反应器的连续化学工艺的放大是化学工程中的一个巨大挑战。典型微反应器的小特征尺寸（<1000 μm）不仅导致微尺度效应（过程强化），而且导致通量低。在这里，我们报告了宏微反应器，以实现液-液化学操作的规模化和过程强化。通过结合基于计算流体动力学设计的内部结 …

Macro-fluidics refers to fluid problems on a macro-scale, ranging between measurements of millimetres to meters. Fluids behave according to the laws of fluid mechanics and fluid dynamics. Scale is an important consideration, as fluids behave differently on very small scales.

2020年11月23日 · To address the scalability of micro-reactor to milli-scale, the liquid–liquid two-phase flow and mass transfer were investigated in the capillary reactor systems with the hydrodynamic diameters of 0.8, 1.6 and 3.0 mm, by varying the superficial liquid velocity and volumetric flux ratio.

2024年12月21日 · Microreactors provide an enhanced mixing performance but suffer from low throughput. This work proposed a macro-microreactor with designed internals to achieve both process intensification and scale-up for the liquid–liquid homogeneous chemical processes. Numerical simulations utilizing computational fluid dynamics were conducted to investigate the fluid mechanics and the properties of ...

2024年5月1日 · Experimental observations of liquid macro superlubricity often involve introducing a small volume of liquid into a macro-scale contact, resulting in film thicknesses or separations of a few nanometers between solid surfaces [5], [6], [7].Importantly, superlubricity is commonly observed in nanoscopic surface roughness conditions, often requiring a …

2025年2月1日 · In this work, a meso-scale flow model of gas-liquid-solid mini-fluidized beds considering macro-scale effects between bed wall and flow is developed based on the principle of meso-scale science and introducing semi-theoretical formulas that take the effects of bed walls on particles and bubbles into account.

AbstractThe scale‐up of microreactor‐based flow chemical process represents a grand challenge in chemical engineering. The small characteristic size (<1000 μm) of a typical microreactor leads to not only microscale effect (process intensification) but also low throughput. Here, we report macro‐microreactor to achieve scale‐up of liquid–liquid chemical operation with process ...
