Efficient heat integration within discretely heat integrated distillation columns using liquid injection

AIChE Journal, Volume 71, Issue 8, August 2025.
Abstract Electrification of distillation processes through discretely heat integrated distillation columns (D‐HIDiC) is an effective approach to enhance energy efficiency and lower carbon emissions. For separating systems with high temperature lift, multi‐stage compression and inter‐stage cooling are necessary to link the high‐pressure rectifier and ...

Transient Characteristics of a Two-Phase Thermosyphon Loop for Multichip Module

ETRI Journal, 1998
A new thermosyphon cooling module (TSCM) has designed, fabricated and tested to cool the multi-chip module consists of a cold plate and an integrated condenser. With an allowable temperature rise of on the surface of the heater, the cooling module TSCM can handle a heat flux of about 2.7 using R11 as working fluid.

Flat Plate Collector Thermal Performance Assessment Using Hybrid MWCNT/Fe3O4/Water Nanofluid for Efficiency Enhancement: An Experimental Study

Engineering Reports, Volume 7, Issue 7, July 2025.
The thermal performance of flat plate collectors (FPCs) was enhanced using nanofluids. A hybrid MWCNT/Fe3O4/water nanofluid achieved 71.9% thermal efficiency, outperforming conventional fluids. Improved Nusselt number, friction factor, and convective heat transfer highlight its effectiveness in optimizing FPC systems. ABSTRACT The flat plate collector (

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, Volume 6, Issue 5, May 2025.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
