Among the various available renewable energy sources such as wind, geothermal, tidal, bio
mass, etc., harnessing of solar energy has become quite popular in most of the countries …

Economic reasons (material and energy saving) leads to make efforts for making more
efficient heat exchange. The heat transfer enhancement techniques are widely used in many …

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

Heat transfer devices have been used for conversion and recovery of heat in many industrial
and domestic applications. Over five decades, there has been concerted effort to develop …

In this paper, simultaneous use of active and passive methods for enhancing the thermal
performance of a double-tube heat exchanger was investigated. This was done by injecting …

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 …

This paper has analysed the effect of the utilization of internal finned tubes for the design of
parabolic trough collectors with computational fluid dynamics tools. Our numerical approach …

The effect of using louvered strip inserts placed in a circular double pipe heat exchanger on
the thermal and flow fields utilizing various types of nanofluids is studied numerically. The …

In this study, the rotating twisted tape and its effect on fluid flow and heat transfer as well as
Performance Evaluation Criterion (PEC) in a tube under constant heat flux is investigated …

In this paper, the experimental effect of the continuous and discontinuous twisted tapes
turbulator (perforated and non-perforated) on the inner side of the internal tube in the double …
