...-mechanical rock properties of laboratory observations. The high temperature decreases the compressive strength, makes the behavior of rock salt become more ductile instead of being brittle. The presence of interlayer induces more complex micro-cracking path, due to the heterogeneous heat transfer. Results...

... to generate electricity, used directly for heating, incorporated into water desalination processes, or used by heat pumps for heating/cooling applications. The present research work examines the possibility of extracting geothermal energy from abandoned oil/gas wells by studying the heat transfer...

... coefficient (function),g- mass coefficient (function),Q- density of the volume flux, V –velocity vector. This equation in specific conditions goes to: - non stationary fluid flow in porous medium (or / and), - mass transport (or /and) - heat transfer (or/and) - vibrating system etc. The paper contains: 1...
