Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 2, Page 167-188, April/June 2025.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

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.

Analytical description of chaotic oscillations in a toroidal thermosyphon

open access: yes, 1995
Multiple time scales and singular perturbation techniques are used to describe the ordinary and the chaotic oscillations due to natural convection in a fluid loop subject to a known external heat flux. The turbulent flow in the loop is modelled using the
