چکیده انگلیسی
In this manuscript we compare very simple physical models and computational simulations with experimental data from polyethylene microspheres on a polished copper surface, with diameters ranging from 20 to 200 μm. Heat transfer through air dominates the process, both for single particles and between particles in clusters. The influence of high particle densities per substrate area on the heat transfer process is factored into the simulation by using a cell with just one particle and symmetric boundary conditions. Further simulations where irregular-shaped carbon pieces were approximated as lying cylinders indicate that our simple model can also describe the thermal behavior of a wider class of realistic particles on solid surfaces.
