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

Solar energy is free, environmentally clean, and therefore it is accepted as one of the most
promising alternative energy sources. The effective use of solar energy is hindered by the …

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 …

An Experimental study has been performed to investigate the heat transfer characteristics
and friction factors of fluid flow through a heat exchanger tube equipped with double-cut …

Experimental investigation of the thermohydraulic characteristics of the circular tube
equipped with alternate clockwise and counter-clockwise twisted-tapes (TA) have been …

This paper aims to present a numerical model for heat transfer intensification in a heat
exchanger tube equipped with novel double V-cut twisted tape. The effects of different cut …

Heat transfer, friction and thermal performance characteristics of CuO/water nanofluid have
been experimentally investigated. The nanofluid was employed in a circular tube equipped …

The turbulent flow and heat transfer characteristics in the Komax static mixer are
experimentally and numerically investigated in the range of Reynolds number (Re) from …

Thermohydraulic performance and second law analysis was applied on the experimental
results by using water/CuO nanofluid, and the rod inserted straight tape (RIST) and the rod …

This paper describes heat transfer enhancement attributed to helically twisted tapes (HTTs).
Each helically twisted tape was fabricated by twisting a straight tape to form a typical twisted …
