Rafid Al-Khoury presents innovative computational modeling of shallow geothermal systems consisting of borehole heat exchangers embedded in a soil mass.

This monograph focuses on the development of a §parameter identification technique for layered §systems on the basis of the spectral element method. §Forward and inverse models are introduced. The §forward model involves the simulation of wave §propagation in elastic, viscoelastic, porous and non-§homogeneous media. The inverse model involves the §utilization of three minimization techniques; §Factored secant update, Levenberg-Marquardt and §Powell hybrid.

A comprehensive mathematical and computational modeling of CO2 Geosequestration and Compressed Air Energy Storage

Energy and environment are two interrelated issues of great concern to modern civilization. As the world population will soon reach eight billion, the demand for energy will dramatically increase, intensifying the use of fossil fuels. Utilization of fossil fuels is by far the largest anthropogenic source of CO2 emission into the earth s atmosphere. This unavoidable reality necessitates efforts to mitigate CO2 from indefi nitely being emitted in...
