Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced 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.

Prediction of NOx Emission Based on Online‐SVR Model Adapts to Ultra‐Supercritical Coal‐Fired Electric Utility Boilers

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
Aiming to address the issue that the performance of the offline model for an ultra‐supercritical coal‐fired power plant boiler gradually degrades after being used for a period under varying operating conditions, this article proposes an online prediction model for NOx concentration based on an adaptive online support vector regression (Online‐SVR ...
