Abstract :

The phenomena of the spreading of liquid on a solid surface are complex. The aerospace industry is moving towards the use of composite materials for carrying of the structure of its aircraft. Different agents are made for facilitating demoulding and applied to the mold before each production cycle of composite aerospace part. This study is outcome of that context studying wetting phenomena in surfaces. We develop a CFD model, to simulate the time evolution of spreading drops on solid surfaces (drop base radius vs. time curve). The effect of wettability of the substrate on droplet spreading is investigated by considering different surfaces. Dynamic surface tension, surfactant adsorption and transport phenomena are included in the computational model. The CFD simulations are quantitatively compared with previously published experimental results from other research groups. Our numerical results compare very well with experimental data.
