In the present study, the effect of twisted tape insert on the wet flue gas condensation in a horizontal tube, as a widely used application of condensation in the presence of non-condensable gas are examined experimentally and numerically. Four...

This paper presents a numerical analysis for Cu-water nanofluid flow through a circular duct inserted with cross-cut twisted tape with alternate axis (CCTA). Three dimensional (RNG) k − ϵ turbulence model is applied to simulate this problem. All...

Optimization and Sensitivity Analysis of a Heat Exchanger Tube Fitted with Cross-cut Twisted Tape with Alternate Axis...

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 ratios (0.6 < b/c<1.8) on the turbulent flow characteristics...

A numerical analysis has been performed to investigate the flow structure and thermal hydraulic performance of turbulent flow through circular tube equipped with twisted tapes with different cut shapes. The geometries of cuts are rectangular...

In this experimental study, hydrothermal characteristics of a U-tube equipped with twisted-tape inserts are

investigated experimentally. The twisting effects of side wall are also investigated for the U-tube as compared to

the smooth...
