"The Emperor's New Clothes: Limitations and challenges of numerical modeling of thermally induced fractures in rock" by Dr. Rennie Kaunda

Tunneling projects can easily cost millions or billions of dollars. These costs can become prohibitive, especially near cities where cost overruns are likely to be borne by taxpayers due to difficult ground. Alternative methods of ground excavation such as mi-crowaves, therefore offer an attractive alternative to traditional mechanical means, resulting in energy and cost savings. Howev-er, a safe and efficient approach to using microwaves for rock fragmentation requires careful laboratory studies and numerical modeling. Unfortunately, the path travelled by numerical modelers is fraught with challenges, which the unsuspecting traveler is prone to. This presentation will present an overview of the current state and limitations of numerical modeling of thermal in-duced fractures. The context will focus on our project on microwave induced thermal damage of rock including methodology, results, challenges and lessons learned.
