Three-dimensional modelling of the free surface turbulent flow of water over a bedform

Sand settling through bedform‐generated turbulence in rivers

“…Venditti, 2007), and by numerical modelling (e.g. Johns and Xing, 1993; Omidyeganeh and Piomelli, 2013; Chen et al ., 2015). Of particular relevance to our study, Lefebvre (2019) used numerical modelling to show that the lateral orientation of the lee‐side slope relative to the mean direction of the flow passing over the bedform is a primary control of the lee‐side flow separation and turbulent wake production.…”

Application of a range of turbulence energy models to the computation of the internal tide

“…The mixing length l 0 can be determined either in terms of an integral of the turbulence energy [7,9,1,39,36] or using an algebraic expression. A simple algebraic form of the mixing length (Johns and Xing [40], referred to later as the JX mixing length) which has been used in a number of tidal calculations [5,6] is given by…”

Pressure Decimation and Interpolation (PDI) method for a baroclinic non-hydrostatic model

“…The approach is suitable for weakly non-hydrostatic flows, assuming that the dominant part of the pressure field is hydrostatic and the non-hydrostatic effects represent a small correction. This straight-forward inclusion of the nonhydrostatic pressure contribution into a hydrostatic model does not require the inversion of a Poisson equation and have been applied to several modeling systems such as in Dietrich and Lin [2002], Johns [1991], Johns and Xing [1993], Li and Johns [2001], and Gaarthuis [1995]. Recently, Klingbeil and Burchard [2013] carried out a validation of the non-hydrostatic capability of the straight-forward method used in the full 3D mode-splitting model GET-M.…”
