What does this research mean for the field?

Among modified twisted tape inserts, the Crosscut Twisted Tape with Alternate Axis (CCTA) design achieves the highest thermal performance factor (1.29) by generating stronger swirl intensity, multiple recirculation zones, and enhanced secondary flows. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Overview

Randomized trial analyzes heat transfer efficiency in circular pipes using modified twisted tapes, indicating optimal designs for better performance.

Key Points

This research aims to evaluate the impact of geometrically modified twisted tapes on heat transfer performance in circular pipes under standardized conditions.
Comparative analysis of three types of twisted tapes: RCT, CRCT, and CCTA.
Optimization of design parameters (length, width, pitch ratio, twist angle) using the Taguchi method.
CFD simulations were conducted to assess thermofluidic performance and thermal performance factor.
CCTA achieved the highest thermal performance factor of 1.29, attributed to effective fluid mixing.
RCT and CRCT showed length of the cut to be the most impactful design parameter for TPF.
For CCTA, the width of the cut contributed 34% and twist angle contributed 33.6% to TPF.
