A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

Chemie Ingenieur Technik, Volume 98, Issue 7, Page 392-405, July 2026.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

Impact of Distillation Column Design on Potential for the Integration of Mechanical Vapor Recompression

Chemie Ingenieur Technik, Volume 98, Issue 7, Page 410-419, July 2026.
Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...

EventFlow: Real‐time neuromorphic event‐driven classification of two‐phase boiling flow regimes

Droplet, Volume 5, Issue 3, July 2026.
We present a real‐time flow regime classification framework that integrates neuromorphic event‐driven sensing with deep recurrent neural networks. Unlike traditional frame‐based approaches, our system captures sparse event streams from an event‐based camera, representing only the dynamic brightness changes at the individual pixel level.

Bubble Collapse in Subcooled Boiling

Bulletin of JSME, 1972
The motion of a vapor bubble in subcooled boiling was studied experimentally using slightly subcooled water, ethanol, and carbon-tetrachloride under the atmospheric pressure. The degree of subcooling ranged usually from about 2°C to 50°C, and in a few extreme cases it was extended to below 1°C. The experimental data for the collapse stage were found to

Assessment of the performance of ultralow‐GWP refrigerants in a two‐stage heat pump system using simulation and MCMD

Environmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract The Kigali Amendment's mandate to phase down high‐GWP refrigerants highlights the urgent need for sustainable alternatives in cold climate heat pumps, which are critical for delivering efficient heating in severely cold regions. This study evaluates ultralow‐GWP refrigerants—R‐290, R‐152a, R‐161, R‐1234yf, and R‐1234ze(E)—for application in a ...
