Abstract :
In this work, an adhesion system for wall climbing robots using vortex cup
has been designed and numerically simulated. A small scale model of the system has
been designed and the
ow patterns including pressure and velocity elds are computed
using CFD analysis. The results are veri ed using mesh independency and validated
through comparison with the available experimental data and show to have high correlation
together. Then a large scale vortex cup based on an actual weight of a wall climbing robot
has been designed and simulated. Furthermore, the e ects of di erent parameters such
as the number of nozzles, cup height and cup radius on the adhesion force have been
studied. Finally, a new cup has been designed base on the optimum data obtained from
the numerical results.
