The thermal energy exchange between a flowing fluid and its confining channel is a
ubiquitous process in modern society. To enhance the fluid-to-wall or wall-to-fluid heat …

Solar thermal systems are advantageous since it is easier to store heat than electricity on a
large scale. As such, concentrated solar power is receiving considerable interest among …

Recent studies in the field of thermal engineering revealed that employing nanofluid as a
working fluid in a specific channel, considering both turbulators and magnetic field effect is …

Enhancing heat transfer surface are used in many engineering applications such as heat
exchanger, air conditioning, chemical reactor and refrigeration systems, hence many …

This work deals with the experimental investigation on Nusselt number, friction factor and
thermal performance factor in a circular tube equipped with perforated twisted tape inserts …

Heat transfer, flow friction and thermal performance factor characteristics in a tube fitted with
delta-winglet twisted tape, using water as working fluid are investigated experimentally …

In the present study, the influences of twin-counter/co-twisted tapes (counter/co-swirl tape)
on heat transfer rate (Nu), friction factor (f) and thermal enhancement index (η) are …

The effect of V-cut twisted tape insert on heat transfer, friction factor and thermal
performance factor characteristics in a circular tube were investigated for three twist ratios …

Heat transfer enhancement is an important matter of concern for energy conservation and
also beneficial from economic point of view. The use of passive devices like twisted tapes …

The main techniques for the enhancement of heat transfer between a solid wall and a fluid
are reviewed for both single phase (liquid and gas) and two-phase (boiling and …
