ABSTRACT

A microstructured glass reactor was investigated by different experimental and theoretical methods to characterize its heat flow and heat transport properties. Calorimetric studies were carried out to measure the heat flow from the microstructured reaction channels to the coolant channels being an integral part of the microreactor. Heat transfer coefficients and transferred heat flows were determined under different flow resp. thermal conditions. It was shown that the integrated cooling structure has a significant influence on the thermal control of the microreaction process. Heat transfer coefficients up to 10, 000 W/m2K can be achieved. Thermography in terms of an infrared imaging system was applied to achieve an online mapping of temperature distributions and temperature profiles over the whole microreaction process. Furthermore, thermography was a suitable tool for monitoring and optimizing process parameters and process conditions like flow rates, retention times, blockages, etc. which influence significantly temperature distributions and heat flow properties of the reactor. CFD simulations of the glass reactor were carried out to confirm the influence of varied process conditions on the microfluidics and mixing performance of the microreactor, and therefore on the heat flow and heat transfer properties of the entire microreaction process.
