Modeling, sensor-based characterization and active control of vaporization processes in microchannel structures

该延续项目的中心目标是扩大针对微反应器中蒸发的理论研究和技术实施。将讨论以下专题：（1）实现电感测的其它原理，（2）在微蒸发反应器中实施的这些传感器的帮助下，进一步改进流动状态的映射（3）实现具有集成微致动器的微蒸发器，用于主动控制和影响蒸发和流动条件（4）对微反应器中的蒸发建模进行了基础研究。有了这些研究，该项目将朝着控制微反应器中蒸发的闭环概念迈出下一步。最终目的是通过主动控制将微反应器中的蒸发过程保持在其理想的过程窗口中，以通过感觉反馈来监测蒸汽质量，并且在高性能冷却的情况下，驱动微蒸发系统朝向高性能。

The central aim of this continuation project is an enlargement of theoretical investigations and technical implementations targeting evaporation in microreactors. The following topics shall be addressed: (1) implementation of further principles of electric sensing, for a characterization of evaporation (2) a further improved mapping of flow regimes with assistance from these sensors implemented in micro evaporation reactors (3) realization of micro evaporators with integrated microactiuators for an active control and influencing of evaporation and flow conditions (4) basic investigations on the modeling of evaporation in microreactors.With that, the project takes the next consequent step towards closed-loop concepts for the control of evaporation in microreactors. The final aim is to keep the evaporation process in a microreactor in its ideal process window, by means of an active control, to monitor steam quality via sensorial feedback and, in the case of high-performance cooling, to drive the microevaporation system towards high performance.
