Finite-Element Modelling of Buoyancy-Driven Flow in Natural Geothermal Systems
MetadataShow full item record
Finite element modelling of buoyancy driven flow in geothermal systems is presented in this thesis. The main focus is on the development of a numerical modelling tool. The program developed is tested for classical benchmarks and correspondence with analytical values for the critical Rayleigh-Darcy numbers for onset of convection and Nusselt numbers for various scenarios is shown.
