Enhancing Efficiency in Double‐Pipe Heat Exchangers: A Detailed Review of NanoFluids and Their Impact on Thermal Performance

open access: yesHeat Transfer, Volume 55, Issue 1, Page 212-240, January 2026.
ABSTRACT This study reviews recent advances in using nanofluids to enhance double‐pipe heat exchanger (DPHE) efficiency. The review examines several types of nanofluids, that is, water‐based graphene oxide and CuO–water nanofluids, assessing their effectiveness under different operating conditions, including inlet temperature and nanoparticle volume ...

Uneven Distribution of Natural Energy Resources Impacts on Systemwide Energy Return on Investment

open access: yesEarth's Future, Volume 14, Issue 1, January 2026.
Abstract Regional disparities in natural energy resources may impede the acceleration of energy transitions in regional power systems, as the shift to net‐zero power systems requires significant energy inputs. Net energy, defined as the surplus remaining after accounting for energy inputs, serves as a key metric of system performance.

Exergy Efficiency of Closed and Unsteady-Flow Systems

open access: yesEntropy
Exergy efficiency is viewed as the degree of approaching reversible operation, with a value of 100 percent for a reversible process characterized by zero entropy generation or equivalently zero exergy destruction since Xdestroyed = T0Sgen.
