TEMPERATURE PROFILE WITHIN A MICROWAVE IRRADIATED BATCH REACTOR

Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 110, Issue 3

Abstract

The finite element method has been used here to investigate the volumetric temperature distribution differences between conventional and microwave heating for a rotating batch reactor containing water-based solutions.It was shown that the temperature distribution is much narrower with microwave heating compared to conventional heating, leading to conditions favourable for process intensification, and uniform particle growth. This effect is particularly pronounced for the first 60 seconds of heating. Thus, some of the claimed „non-thermal” microwave effects could be explained considering the different temperature distribution in the reaction volume for the two types of reactors, i.e. they can be ascribed to purely thermal effects.The computer simulations included 3D modeling, coupling with fluid-dynamics, heat transfer, and electromagnetic analysis, with insertion of a large number of not perturbative “virtual” temperature probes in the reactors.
