Abstract Data-driven models can predict, estimate, and monitor any highly nonlinear multi-variable behaviour of high-temperature superconducting (HTS) materials, devices to analyse their characteristics with a very high accuracy in an almost real-time procedure, which is significant figure merit as compared traditional numerical approaches. The electromechanical twisted HTS tapes under differen...

background and aims. the manufacturing process of rotary ni-ti file can influence its resistance to fracture. the rotary profile (dentsply-maillefer, baillagues, switzerland) is manufactured by grinding mechanism whereas twisted file (sybron endo, usa) is manufactured with a twisting method. the purpose of this study was to comparatively evaluate the effect of manufacturing process on distortio...

YBa2Cu3O7-X tapes fabricated from precursor powder, were used to investigate the effect of sintering conditions on the microstructure. The sintering experiments were carried out in oxygen over the temperature range of 915-950ْC. Scanning electron microscopy was used to examine the sintered products. The result indicated a significant increase in densification and grain growth when the tapes were...

Improvements in miniaturization and boosting the thermal performance of energy conservation systems call for innovative techniques to enhance heat transfer. Heat transfer enhancement methods have attracted a great deal attention industrial sector due their ability provide savings, encourage proper use sources, increase economic efficiency systems. These are categorized into active, passive, com...

Abstract This study is conducted to investigate the effect of off-center placement twisted tape on flow distribution and heat transfer in a circular tube. The width 20, 18, 16, 14 12 mm performance discussed under same twist ratio 2.0. numerical analysis field, average Nusselt number, friction factor thermo-hydraulic parameter tube are with Reynolds number ranged from 2600 8760. results indicat...

This paper presents a numerical investigation on heat transfer enhancement by using computational fluid dynamics software. The is implemented inserting twisted tape into exchanger tube. tapes with twist ratios of 4, 6 and 8 were modified alternate axis. pitch the having rotation direction such as clockwise counterclockwise are connected 90º connection angle. Water selected working turbulent flo...

In this paper, experimentally derived correlations of heat transfer and pressure drop are used in a Pareto based Multi-Objective Optimization (MOO) approach to find the best possible combinations of heat transfer and pressure drop of TiO2-water nanofluid flow in tubes fitted with multiple twisted tape inserts in different arrangement. In this study there are four independent design variables: t...
