The paper “Numerical simulations of shallow-water sloshing coupled to horizontal vessel motion in the presence of a time-dependent porous baffle” authored by Matt Turner has been accepted for publication in the Journal of Engineering Mathematics. This paper numerically simulates the motion of a coupled fluid system which includes a porous baffle whose porosity can be controlled. Solutions are considered in the shallow-water system so that the Lagrangian Particle Path approach can be utilized and hence a symplectic numerical scheme can be used. Results show that time-periodically oscillating the porosity of the baffle can cause the system to lose energy faster than the same system with a fixed porosity baffle. Figure 16 from the paper showing regions of parameter space where the decay rate of the time-periodic baffle is larger than the fixed baffle is shown below.
