Dam-break reflection (2021)
Journal Article
Hogg, A. J., & Skevington, E. W. G. (2021). Dam-break reflection. Quarterly Journal of Mechanics and Applied Mathematics, 74(4), 441-465. https://doi.org/10.1093/qjmam/hbab010

The unsteady reflection of dam-break flow along a horizontal channel by a remote barrier is modelled using the nonlinear shallow water equations. The interaction generates an upstream moving bore that connects the collapsing reservoir of fluid to a r... Read More about Dam-break reflection.

Development of supercritical motion and internal jumps within lock-release radial currents and draining flows (2021)
Journal Article
Skevington, E. W. G., Hogg, A. J., & Ungarish, M. (2021). Development of supercritical motion and internal jumps within lock-release radial currents and draining flows. Physical Review Fluids, 6(6), Article 063803. https://doi.org/10.1103/physrevfluids.6.063803

The unsteady radial flow of a relatively dense fluid released from an axisymmetric lock is analyzed when it freely drains over an edge and when it generates a gravity current propagating over a horizontal surface. In both situations when modeled usin... Read More about Development of supercritical motion and internal jumps within lock-release radial currents and draining flows.

Unsteady draining of reservoirs over weirs and through constrictions (2019)
Journal Article
Skevington, E. W. G., & Hogg, A. J. (2020). Unsteady draining of reservoirs over weirs and through constrictions. Journal of Fluid Mechanics, 882, Article A9. https://doi.org/10.1017/jfm.2019.808

The gravitationally driven flow of fluid from a reservoir following the partial collapse of its confining dam, or the partial opening of its confining lock, is modelled using the nonlinear shallow water equations, coupled to outflow conditions, in wh...
