A Generic Framework for Multiscale Simulation of High and Low Enthalpy Fractured Geothermal Reservoirs under Varying Thermodynamic Conditions

We develop a multiscale simulation strategy, namely, algebraic dynamic multilevel (ADM) method, for simulation of fluid flow and heat transfer in fractured geothermal reservoirs under varying thermodynamic conditions. Fractures with varying conductivities are modeled using the projection-based embedded discrete fracture model (pEDFM) in an...

From gas to geothermal energy: Adaptations at building level for a lower temperature in the heating network

The transition from fossil fuels to renewable energy sources brings along the reduction of the supply temperature of the distribution heating networks, because renewable energy sources usually provide heat at lower temperatures. This master thesis specifically focuses on the buildings because it is uncertain which adaptations are necessary to...

Assessment of the effect of groundwater flow on the performance of Borehole Thermal Energy Storage systems

In a Borehole Thermal Energy Storage (BTES) system, heat is extracted from or injected to the subsurface, taking advantage of the relatively constant temperatures of the underground. Both thermal conduction and advection can influence the performance of BTES systems, but thermal advection is often neglected in the design process. However, in...

Thermally-enhanced oil recovery from stranded fields: Synergy potential for geothermal and oil exploitation

Design of a Heating System with Geothermal Energy and CO2 Capture

Heating constitutes about 40% of the final energy consumption at TU Delft. In the present, the district heating system in campus obtains its energy from the combustion of natural gas in a combined heat and power plant. Although this plant produces heat and electricity with an efficiency over 80%, the dependance on a fossil fuel presents an...

Adaptive Multiscale Finite Element Method for Subsurface Flow Simulation

Natural geological formations generally show multiscale structural and functional heterogeneity evolving over many orders of magnitude in space and time. In subsurface hydrological simulations the geological model focuses on the structural hierarchy of physical sub units and the flow model addresses the functional hierarchy of the flow process....

An extension of Lauwerier’s Solution for heat flow in saturated porous media

One of the crucial topics in this century is sustainable energy. Since the sources of fossil fuels are limited and are going to be exhausted, there is a need to look for sustainable renewable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of...
