Transient effects in geothermal convective systems.

by Horne, Roland Nicholas

Abstract (Summary)
This work is a detailed analysis of the transient behaviour of geothermal convective systems. The flow in these systems is found to be fluctuating or regular oscillatory in a simplified two-dimensional model and these unsteady effects persist when the model is refined to include the concepts of temperature dependent viscosity and fluid withdrawal and recharge. The analysis is extended into three dimensions to verify this behaviour. The supplementary exploration of added salinity gradients indicates transient effects of a different kind in this case. The examination of the porous insulator problem confirms the results of previous authors and verifies the viability of the numerical methods that are used throughout the investigation.
