abstract
2016 American Automatic Control Council (AACC). In this paper we consider modeling of temperature distribution in moving webs due to heating by radiation panels. We develop a web heat transfer model by considering radiation from the heating panels and convection on the surface of moving webs. We address the issue of convection coefficient changes with web temperature. Using this model, one can predict the web temperature in the moving web at different speeds. The model development and analysis is dimensionless, so it can be applicable to a variety of web materials and heating panel locations. The modeling is motivated by R2R ALD/MLD application and an experimental platform designed to conduct ALD/MLD is employed to validate the model for different scenarios. Comparative results from experiments and model simulations for varying speeds and different operating conditions are provided to validate the model.
