We present experiments and Surface Evolver simulations concerning the interaction of fibres with simple arrangements of soap films, which constitute model systems for dry foams. For a fibre inserted into a soap film which spans two Plateau borders, our simulation accurately predicts the variation in the length of the film as the fibre thickness is varied. For a fibre introduced into a Plateau border, simulations accurately predict the variation in length of the Plateau border as the fibre diameter is varied, and as it is moved. We suggest that the force necessary to move the fibre from equilibrium may act to inhibit foam coarsening, in line with observations from experiments on fibreladen foams.
EUFOAM Proceedings OfficeDublin, 28/10/2016 Dear Editor, Please find enclosed our manuscript entitled: "Interactions of fibres with simple arrangements of soap films" which was presented in the last EUFOAM Conference by David Whyte. This work presents an experimental investigation of the configuration of soap films in the presence of fibre. The data are described both theoretically and numerically. The very good description of our experimental data with our simulations allow to predict the configuration of the films as a function of the features of the fibre.In addition, our observations raise the question of the interaction between foam and fibres at the macroscopic scale, this appears as a promising topic, in particular for industry dealing with novel materials. Thus, we believe our observations should interest the broad community of researcher in fluid mechanics working on foam containing solid material. We therefore would be very excited to see this work published in the EUFOAM Proceedings, which we believe reaches the most relevant audience for our work.
AbstractWe present experiments and Surface Evolver simulations concerning the interaction of fibres with simple arrangements of soap films, which constitute model systems for dry foams. For a fibre inserted into a soap film which spans two Plateau borders, our simulation accurately predicts the variation in the length of the film as the fibre thickness is varied. For a fibre introduced into a Plateau border, simulations accurately predict the variation in length of the Plateau border as the fibre diameter is varied, and as it is moved. We suggest that the force necessary to move the fibre from its equilibrium position may act to inhibit foam coarsening, in line with previous observations from experiments on fibre-laden foams.
