Eﬀects of packer locations on downhole electric heater performance : experimental test and economic analysis
A downhole electric heater, which reduces heat loss along a heat insulation pipe, is a key apparatus used to ignite oil shale underground. Downhole heaters working together with packers can improve the heating efficiency ...
An experimental study on the drying-out ability of highly insulated wall structures with built-in moisture and rain leakage
The recent research on highly insulated structures presents controversial conclusions on risks in moisture safety. This paper addresses these controversial issues through investigating the hygrothermal performance of energy ...
