Enhanced multimaterial 4D printing with active hinges

TL;DR: In this paper, the authors used multimaterial inkjet 3D printing technology to fabricate shape memory structures, including a morphing wing flap and a deployable structure, which consist of active and flexible hinges joining rigid (non-active) parts.

Thermal and hydraulic characteristics of nanofluid flow in a helically coiled tube heat exchanger

TL;DR: In this article, the effects of using different geometrical parameters with the combination of nanofluid on heat transfer and fluid flow characteristics in a helically coiled tube heat exchanger (HCTHE) are numerically investigated.
Journal ArticleDOI

An experimental study on heat transfer and pressure drop characteristics of decaying swirl flow through a circular pipe with a vortex generator

TL;DR: In this article, an experimental study is carried out to investigate heat transfer and pressure drop characteristics of a decaying swirl flow in a horizontal pipe, which is produced by the insertion of vortex generators with propeller-type geometry, a kind of passive heat enhancement tools.
Journal ArticleDOI

Study of different heat exchange technologies influence on the performance of thermoelectric generators

TL;DR: In this paper, the authors investigated the differences as well as the advantages and disadvantages of three typical heat exchangers in a thermoelectric setup, and the power consumed by the auxiliary equipment to improve the performance were taken into account.

Energy and exergy analysis of a new solar air heater with latent storage energy

TL;DR: In this article, a new solar air heater with a packed-bed latent storage energy system using PCM spherical capsules was proposed, and the experimental results were used to analyze the performance of the system, based on temperature distribution in different parts of the collectors, absorbed, instantaneous stored and used thermal energy.
