Livrables

Project and data management plan (s’ouvre dans une nouvelle fenêtre)

The deliverable will contain the Project and data management plans in a single report. The DMP will describe how the data will be managed in a secure, reproducible auditable and compliant manner following the FAIR principles. The project management plan will consist of the integrative management which is consolidated at different processes: cost, resources, communication, content and delay, risk, purchase and legal aspects.Will also address open access to research data, and explain how to deal with it. The Data management plan will address and guarantee open access to research data.

Benchmark cases (s’ouvre dans une nouvelle fenêtre)

Procedures for benchmarking geothermal simulators will be developed in the task. Building analytical solutions for the temperature in an injection well and the surrounding rock, we will define cases for software validation.

Optimized design for the closed loop geothermal system (s’ouvre dans une nouvelle fenêtre)

We will run a series of numerical simulations of different well designs to find the optimal design with regard to different well-depth, length, diameter, rock properties, fluid circulation rates and tubing properties. The simulations will quantify the decline in power over years of production. We expect the results to show that quite different well designs may produce nearly the same power. The optimal well designs form the basis for the development of actual sites.

Flow pipe model for fluid circulation (s’ouvre dans une nouvelle fenêtre)

The report will contain a description of the different available tools for well modeling and results for different well configurations using water as pipe-fluid. The available models for the heat flow towards geothermal well from Task 2.1 will be integrated in models for the heat and fluid flow in the annulus and the central pipe. We will see how a model for heat flow towards a geothermal well can be coupled with advanced state-of-the-art models for pipe flow, either commercial software (i.e., OLGA Dynamic Multiphase Flow Simulator) or in-house tools. Using CFD advanced models for the pipe flow, we will predict the flow regime in the pipes, in case of multiphase flows, and test the heat transfer coefficients that control the heat flow from the well-wall interface to the fluid. We will add details to the numerical grids for better resolution of the heat flow between the inner tube and the annulus and the structure of the near well area.
