Temperature monitoring using Distributed Temperature Sensing (DTS) technology

Energy Procedia, 2014
AbstractThe applicability of Distributed Temperature Sensing (DTS) as a technology to monitor CO2 flow within CO2 injection zones at the inter-well scale, as well as to detect CO2 leakage into the overburden, is studied in this paper An onshore CO2 injection site in the U.S.

Green Compact Temperature Evolution during Current-Activated Tip-Based Sintering (CATS) of Nickel

Metals, 2013
Current-activated tip-based sintering (CATS) is a novel process where spark plasma sintering conditions are applied through an electrically conducting tip on a locally controlled area on a green powder compact/bed. The localization of electric current in
