      Implementation or partial-element wetting and drying in 1D ADCIRC results in improved wetting front propagation and mass balance compared with the previous algorithm, which treats entire elements as either wet or dry. Partial-element wetting and drying is achieved by applying a scaling factor to the primitive continuity prior to formulation of the generalized wave continuity equation.

      A general procedure has been developed for the simulation of charged liquid and electrostatically atomized sprays. The procedure was validated through simulations of previously published charged spray experiments. Results successfully showed that the general spatial characteristics and dynamics of a charged liquid spray can be reproduced, including the axial and radial dispersal patterns of droplets and the distribution of mean droplet diameters throughout the spray plume.

    4. Numerical study of radial basis function interpolation for data transfer across discontinuous mesh interfaces (pages 1076–1095)

      A numerical study is presented of a universal method for interpolating solution data across discontinuous mesh interfaces. The method utilises radial basis functions for n-dimensional volume interpolation. It is shown that high spatial order data transmission is achievable for a modest computational overhead.

      Kidder's isentropic compression problem. Comparison of the analytical result (solid line) with the numerical results computed by the scheme of Maire et al. and by the current entropy fixed scheme for the density at t = 0.99 with a grid nx = 25, ny = 44.
