Propagation of plane elastic waves in an infinite porous medium containing two immiscible fluids has been investigated. Four plane waves can propagate with distinct phase speeds in such a medium. Out of these four waves-three are compressional waves and one is transverse wave. Out of these four waves, two compressional waves and one transverse wave are the same waves earlier encountered by Biot in the porous medium saturated by single fluid. The appearance of the third compressional wave is new and arises due to the presence of second fluid in the medium. Using potential method, reflection and transmission of plane waves is studied at elastic/porous and porous/porous plane interface. The effect of inertial coupling is noticed on the reflection/transmission coefficients at elastic/porous interface.The possibility of plane wave propagation has also been studied in fractured porous medium containing two immiscible fluids. The reflection/transmission phenomena are also investigated at elastic/fractured porous interface. Lastly, the dispersion equation of stoneley type surface waves has been investigated at the boundary of a cylindrical borehole in a porous medium containing two fluids.

This comprehensive resource caters to system designers that are looking to incorporate lithium ion (li-ion) batteries in their applications. Detailed discussion of the various system considerations that must be addressed at the design stage to reduce the risk of failures in the field is presented. The book includes technical details of all state-of-the-art Li-on energy storage subsystems and their requirements, and provides a system designer a single resource detailing all of the common issues navigated when using Li-ion batteries to reduce the risk of field failures.The book details the various industry standards that are applicable to the subsystems of Li-ion energy storage systems and how the requirements of these standards may impact the design of their system. Checklists are included to help readers evaluate their own battery system designs and identify gaps in the designs that increase the risk of field failures. The book is packed with numerous examples of issues that have caused field failures and how a proper design/assembly process could have reduced the risk of these failures.
