Twente mass and heat transfer water tunnel: Temperature controlled turbulent multiphase channel flow with heat and mass transfer [PDF]

open access: yesReview of Scientific Instruments, 2019
A new vertical water tunnel with global temperature control and the possibility for bubble and local heat and mass injection has been designed and constructed. The new facility offers the possibility to accurately study heat and mass transfer in turbulent multiphase flow (gas volume fraction up to 8%) with a Reynolds-number range from 1.5 × 104 to 3 ...

Fast Calculation of Supercritical Carbon Dioxide Flow, Heat Transfer Performance, and Mass Flow Rate Matching Optimization of Printed Circuit Heat Exchangers Used as Recuperators

open access: yesMathematics, 2023
Printed circuit heat exchangers (PCHEs) are widely used as recuperators in the supercritical carbon dioxide (S-CO2) Brayton cycle design. The variation of heat sources will have a great impact on the heat transfer effect of the recuperator.

A review: Analysis and development of heat–mass synergy theory

open access: yesEnergy Reports, 2022
In this work, a review of the theory and application of heat and mass synergy is carried out. Since the field synergy theory was proposed, it has not only been greatly developed in the field of heat transfer but also has been explored and studied in the ...
