The analysis starts from the kernel-based approximations inherent to the SPH method. An explicit kernel correction is proposed, which approximately achieves first-order consistency. The suggested approach is additionally combined with a Eulerian variable resolution approach, which conserves the number of particles but changes the individual particle mass in a transit regime. Validation studies featuring fully wetted and free-surface flow configurations are employed to assess the benefits of the combined approach. Results indicate benefits of the kernel correction and display merits and drawbacks of the variable resolution approach.||URI:||http://hdl.handle.net/11420/2902||ISSN:||0955-7997||Institute:||Fluiddynamik und Schiffstheorie M-8||Type:||(wissenschaftlicher) Artikel|
