报告内容：
Geothermal energy production requires a high permeability heat exchange from deep hot rocks. The typical procedure locates naturally pre-existing discontinuities, such as faults and joints, and enhances heat permeability by means of hydraulic stimulation. This is a basic scenario for Enhanced Geothermal System(EGS). In this lecture I will talk about mathematical modelling equations for Thermal Variations between fracture and rock zones due to the water injection in the enhanced geothermal system(EGS). As a mechanical reason for Pohang Earthquake I emphasize that thermalelastics is an essential ingredient in causing such large magnitude of stress, because Pohang Earthquake occurred two months later after Pohang EGS stops water injection. Also I will give interface corner singularity functions from the interface and boundary value problem and discuss about increased regularity for smoother part. I will also talk about the stress variations related to the compressible Navier-Stokes flows on the polygonal domains with inflow and outflow conditions.
