The present paper discusses film cooling behavior through numerical simulation in the presence of a twisted tape insert inside hole. imparts swirl to coolant flow. Coolant intensity is controlled by varying pitch resulting numbers 0.0289, 0.116, and 0.168. performance evaluated using area-averaged effectiveness heat transfer coefficient for blowing ratios 0.5, 1.0, 1.5, 2.0. Results revealed si...

Features of the tubular type heat exchanger were examined experimentally in current study. A rig is fitted with a novel insert as negative transfer increase technique. The core fluid used air under steady flux and turbulent discharge state (6000 ≤ Re 19,500) conditions. Two augmentation inserts are employed; one basket turbulators utilized turbulator placed inside constant pitch ratio (PR = 150...

This article presents the application of machine learning (ML) algorithms in modeling heat transfer correlations (e.g., Nusselt number and friction factor) for a exchanger with twisted tape inserts. The experimental data at different Reynolds numbers (Re), twist ratio (t), percentage perforation (p), varied tapes (n) were used correlation modeling. Three ML algorithms: polynomial regression (PR...

This article presents the results of an analysis heat enhancement intensification using twisted tapes in linear absorbers for low-concentration parabolic trough collectors, a technology frequently considered as supplementary energy source industrial production. contribution proposes segmented application different to intensify absorption. A 33.7 mm tubular absorber placed collector focal point ...

Abstract This work investigates heat transfer and entropy generation of a turbulent flow an Al 2 O 3 –Cu/water hybrid nanofluid in plain tube (PT) with classical (TPT) elliptical‑cut twisted tape (TECT) inserts. The pressure drop are investigated numerically at Re (7000–15,000), mass concentration (1–4%), the inlet temperature fluid (300 K). Further, total Bejan number examined = 7000 4%. obtai...

In this study, the heat transfer rate of Al2O3-water nanofluid-flow in a tube with twisted tape inserts is experimentally examined. The insert can cause swirling region fluid-flow which will enhance coefficient. On other hand, have great influence on pressure drop. It known that nanoparticles and may both increase fluid. Thus, it tried to demonstrate combined effect phenomena, experimentally. w...
