Rotating steel plate energy storage

Can active rotation improve heat transfer efficiency in phase change systems?

Introducing active rotation can effectively enhance the heat storage rate in phase change systems. This study presents a novel triplex-tube latent heat storage unit with a rotating middle tube and coupled V-fin to improve heat transfer efficiency through active rotation.

How to evaluate the performance of energy storage flywheels?

To increase the performance of the flywheel, the energy density (the stored energy per unit mass) (Bolund et al. 2007), e, is one of the essential parameters to evaluate the performance of energy storage flywheels. The energy density of a flywheel rotor is given as follows:

Why is latent heat storage a hot topic?

Because of its high energy density, reliable temperature regulation, controllability, and cheap operating costs, latent heat storage is now a hot topic in the study , . In order to store and release thermal energy, the phase change thermal storage technique uses PCM.

What are the different types of thermal energy storage technology?

Because of its simple design, low cost, and great efficiency, thermal energy storage technology has attracted a lot of interest , . Sensible heat storage, latent heat storage, and thermochemical storage are the three main categories under which this technique falls.

How does a phase change heat storage structure affect performance?

Studied the effect of fin structure variations coupled with rotation on performance. Applied machine learning algorithms for multi-objective optimization of the structure. Phase change heat storage technology faces challenges such as slow heat transfer rates and uneven melting, limiting its performance.

Does rotational technology improve melting rates and heat transfer?

Velocity distribution results indicate that at n = 2 rps, the external velocity reaches 0.9 m/s, which is significantly higher than the near-zero velocity observed under static conditions. This highlights the advantages of rotational technology in enhancing melting rates and external heat transfer.
