Abstract
Aiming to model drying processes in automotive industry, numerical investigations of turbulent heat transfer in a laboratory dryer and an industrial dryer have been carried out using CFD. Flat sheets, a 3-D driver's cab model, as well as more complicated geometries of substrates, for instance, a real car body were used in the simulations. The suitable turbulence model and appropriate grid resolutions were applied for the present industrial computations. The calculated heating-up behaviour on substrates was compared with experimental results. The distribution of local temperature gradients obtained in CFD calculations can be used to develop models for predicting paint film defects in drying processes.
