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.

Selective Internal Heat Distribution in Modified Trombe Wall

IOP Conference Series: Earth and Environmental Science, 2017
At present, the requirements for thermal insulation of the external walls in buildings are being increased. There is a need to reduce energy consumption for heating rooms during the winter season. This may be achieved by increasing the thermal resistance of the outer partitions, using solutions that utilize either recuperation or solar radiation.
