Subject: Two-Phase Modeling for sediment transport in estuaries: turbulent Modeling for solid phase by LES Approach
Objectives
The two-phase modeling allows a fine description of mechanisms that govern sediment transport such as fluid-particle and particle-particle interactions including the process of deposition, erosion, compaction and consolidation. The two-phase model is based on solving of the Navier-Stokes equations for both the fluid and the solid phases with their constitutive laws. Simulation results, recently obtained by Julien Chauchat (2007) showed that non-Newtonian rheological law (law of viscosity depending on the density) is sufficient to describe the motion of a turbidity maximum in estuaries. Thus no parameterization of exchanges between the bottom and water column, is required for such models.
The ongoing works of the LHSV (Laboratory for Hydraulics Saint-Venant) are: (i) introduction of a permeability and an effective stress laws for a detailed description of the hindered settling and the consolidation regimes, (ii) application of two phase model for the displacement of the turbidity maximum in the Seine and the Gironde estuaries, (iii) applying the two-phase model for dumping dredged sediment in the sea and (iv) optimization of the code computing (parallelization).
The PhD thesis proposed herein aims to develop a turbulence model for the solid phase. The objective of this work is accounting for the above-mentioned contexts and aims to: i) deepen our understanding on turbulence modeling for the solid phase and develop a turbulence-closure sub-model which will be able to correctly describe turbulent laden flows (in the dilute and dense regimes); ii) validate the developed new model for academic test case and applied to a real estuary.
Method
The research will be based on works carried out under the previous collaborations between University of Caen Basse-Normandie - Ecole des Ponts ParisTech – CETMEF, which is focused on the development of a two-phase model applied to sediment transport. A literature review on the state of the art on the two-phase turbulence modeling will be conducted to propose appropriated theories, especially LES approaches, concerning the solid turbulent modeling. Turbulent sub-models for solid phase will be developed, tested and validated. Finally, an application to real sites is proposed.
Deliverables
- Literature review on the turbulence modeling in the two-phase approach.
- Test case results using the selected models of turbulence.
- Analysis on selected models with conclusion on the choice of model to be used.
- FORTRAN code models of turbulence.
Skills required
- Fluid Mechanics
- Numerical Methods in FORTRAN or C
- Parallel computation (optional)
Location / Salary
The PhD thesis will be prepared at the Université Paris-Est, Laboratory of Hydraulics Saint-Venant, based in Chatou, Parisian Region. It is accessible by the RER A line (20 min from Paris center). The doctoral scholarship from the Ecole des Ponts (1650 € net / month for 36 months) is acquired for this work.

This issue of AHEM contains a series of papers constituting a part of the scientific material presented and discussed during the Polish-Russian Conference entitled “Coastal hydro-, litho- and morphodynamics in the east part of the Gulf of Gdansk”. The Conference was organised in Lubiatowo, nearby the IBWPAN Coastal Research Station (CRS), in the period from 25 to 28 May 2010.
A major objective of the event was to sum up recent studies by Russian and Polish researchers relating to the Conference topic. These studies, both theoretical and experimental, have been conducted for many years within a few Polish and Russian national projects, as well as under auspices of the joint Polish-Russian bilateral cooperation. One should acknowledge the latest project conducted under the agreement on scientific cooperation between the Polish Academy of Sciences and the Russian Academy of Sciences, namely “Dynamics of non-tidal shores and river mouths under anthropogenic pressure” (2008–2010) which will be followed by “Development of the scientific basis for shore protection of the South Baltic coast” (2011–2013). From the Polish party, this collaboration has been coordinated by Professor Zbigniew Pruszak (IBW PAN) while on the Russian side it has been led by Professor Ruben Kosyan (P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences, Southern Branch in Gelendzhik – SB IO RAS) until 2010 and will be coordinated by Dr. Boris Chubarenko (P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences, Atlantic Branch in Kaliningrad – AB IO RAS).
The Polish-Russian joint investigations, especially the ones concerning trans- -boundary issues relating to the Gulf of Gdansk and the Vistula Lagoon, have been possible due to a series of Agreements on the bilateral co-operation between AB IO RAS and IBW PAN, comprising the periods 2005–2008, 2009–2010 and 2010–2014 (the latter signed on 2nd March 2010).
The Conference in Lubiatowo was preceded by extensive theoretical research and field surveys carried out in the period from autumn 2008 to late spring 2010. They were partly sponsored by Russian domestic projects and partly by the Polish Ministry of Science and Higher Education under the project N N306 280535, entitled “Variability of hydrodynamic and lithodynamic coastal processes in the east part of the Gulf of Gdansk”. In the course of the studies and analyses, a thorough review of available literature has been conducted and a lot of archival data have been processed and exchanged between the parties. Mathematical models have been applied to determine parameters of the physical coastal processes in the east part of the Gulf of Gdansk. In addition, joint Polish-Russian in situ investigations were carried out twice – in November 2008 (in the Polish part of the Vistula Spit) and in August 2009 (along the entire Russian coast of the Gulf of Gdansk).
The research activities summarised at the Conference could never have been successful without enormous help from the coastal authorities, both in Russia and Poland. Considerable support from their representatives in the form of coastal engineering knowledge and field data was provided both before and during the Conference in which, aside from scientists from IBWPAN and AB IO RAS, the Polish and the Russian coastal officials took part. This group of experts was represented, among others, by the Chief Inspector of Coastal Protection and the Chief Specialist on Coastal Spatial Planning from the Maritime Office in Gdynia (the Polish coastal authority subject to the Ministry of Infrastructure) and the delegation from “Baltberegozashchita” in Kaliningrad (the Russian counterpart of the Polish Inspectorate of Coastal Protection in the Maritime Office), including the Director of this coastal administrative entity in the Russian Federation (Kaliningrad Oblast).
The Conference presentations and discussions were focused on qualitative and quantitative findings on the wave climate and longshore sediment transport in the east part of the Gulf of Gdansk, as well as on practical coastal engineering issues related to hydrodynamic, lithodynamic and morphodynamic phenomena in the region.
An additional session of the Conference was also held, during which participants visited the Coastal Research Station (CRS) in Lubiatowo. During this session, results of field surveys carried out in recent years were presented, together with research plans for the coming years.
The Conference was a good opportunity to discuss prospects on further joint research ventures within various programmes and projects, both national and European.
Additionally, one day of the Conference was devoted to a technical trip during which the participants had an opportunity to get acquainted with a variety of coastal protection measures undertaken on the shores of the Hel Peninsula and at the cliff in Jastrzebia Góra.
