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.

Void fraction thermo-kinematics for subcooled flow boiling

Physics of Fluids, 2022
This work presents some preliminary results about a new void fraction model in subcooled flow boiling based on brand new mass and energy balances developed by the author over the past years. As main novelties, the new mass balance is based on the liquid velocity and the mixture specific volume, whereas the new heat balance is a function of the mixture ...

An investigation on hydrate prediction and inhibition: An industrial case study

The Canadian Journal of Chemical Engineering, Volume 103, Issue 1, Page 396-409, January 2025.
Abstract This investigation reports the first study to predict natural gas hydrate formation using both Aspen HYSYS® and HydraFlash software for various gas compositions and thermodynamic inhibitors (monoethylene glycol [MEG] concentrations at 10, 20, 30, and 40 wt.% and methanol concentrations at 10 and 20 wt.%). The simulated predictions are compared

Interfacial Heat Transfer of Condensation Bubble with Consideration of Bubble Number Distribution in Subcooled Flow Boiling

Journal of Thermal Science and Technology, 2013
For predicting the void fraction distribution in subcooled flow boiling, it is necessary to measure the interfacial heat transfer coefficient—which determines the amount of condensation rate of vapor bubble—with high accuracy.
