This is version 2.1 of the MatRANS model, for simulating simple one-dimensional vertical (1DV) boundary layer flows in Matlab. The model solves unsteady Reynolds-averaged Navier-Stokes (RANS) equations, coupled with k-omega turbulence model closure, coupled with bed and suspended load sediment transport models.

The model is intended to be utilized within selected hands-on exercises (Chapter 10) in the text book:

Sumer, B.M. and Fuhrman, D.R. (2020) Turbulence in Coastal and Civil Engineering. World Scientific. DOI: 10.1142/10829

Cases set up as described in the book can be found in the MatRANS/TurbulenceBook directory.

The hydrodynamic and turbulence models are also described in Section 5.12 in the book above.


The basic model (turbulence model and sediment transport) is originally described in:

Fuhrman, D.R., Schløer, S. and Sterner, J. (2013) RANS-based simulation of turbulent wave boundary layer and sheet-flow sediment transport processes. Coast. Eng. 73, 151-166. DOI: 10.1016/j.coastaleng.2012.11.001

Extension to include a transitional turbulence model is described in:

Williams, I.A. and Fuhrman, D.R. (2016) Numerical simulation of tsunami-scale wave boundary layers. Coast. Eng. 110, 17-31. DOI: 10.1016/j.coastaleng.2015.12.002

Extension to include transport of graded sediment mixtures is described in:

Caliskan, U. and Fuhrman, D.R. (2017) RANS-based simulation of wave-induced sheet-flow transport of graded sediments. Coast. Eng. 121, 90-102. DOI: 10.1016/j.coastaleng.2016.11.007

Several additional examples (involving steady and unsteady boundary layer flows, as well as sediment transport) are included in the MatRANS/Examples directory.
