Effects 0f Microfluidics on Preparative Chemistry Processes

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

This chapter deals with the effects of microfluidics on preparative chemistry processes. The main characteristic features of microstructured reactors (MSR) are their high surface area-to-volume ratio in the range from 10000 to 50000 m2/m3. Various paramete ...

Analytical method to predict two-phase flow pattern in horizontal micro-capillaries

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

An a priori prediction of multiphase flow pattern in micro-capillaries or microstructured reactors (MSR) is required for their rational design. The state-of-the-art numerical models require huge computational efforts. In the present work, an analytical mod ...

Mixing efficiency and energy consumption for five generic microchannel designs

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

Mixing is an essential part of chemical processes. In the present work, homogeneous mixing at relatively high throughput for a single microchannel (of 1-18 mL/min) was investigated in microchannels with different dimensions, cross sections and mixing eleme ...
