Internal structure of the energy storage tank

How many models based on different fin configuration of energy storage tank?

Six models based on different fin configuration of the energy storage tank with phase change material were established. The fin structure of model 3 is designed by topology optimization method. The thermal storage and release process of the six models were calculated by numerical simulation method.

What is the energy consumption evaluation index of storage tank heating process?

Moreover, the energy consumption evaluation index of the storage tank heating process is established, and the energy consumption mechanism accounting for the tank oil level, the coil heat flow density and the external environmental conditions for the heating process with different coil structures is proposed.

How does a storage tank heating process work?

Theoretical model for the heating process with a storage tank coil During the tank heating process, crude oil can exchange heat depending on the external dynamic environments. In this process, a high-temperature coil heats the oil in the tank, which increases the temperature of the oil near the coil and gradually decreases its density.

What are the three methods of thermal energy storage?

It is well known that there are three methods for TES at temperatures from—40 °C to more than 400 °C: sensible heat, latent heat associated with PCMs, and thermo-chemical storage associated with chemical reactions (Fig. 7.2) . Methods of thermal energy storage: a sensible heat; b latent heat; c thermochemical reactions

What is energy storage?

Energy storage has become an important part in renewable energy technology systems such as solar systems. TES is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation.

What is a coil heating theoretical model of a large crude oil storage tank?

The variable physical parameters of crude oil and dynamic thermal environment are considered to establish a coil heating theoretical model of a large crude oil storage tank. On this basis, according to the first and second laws of thermodynamics, the energy loss mechanism of the multiple links in the heating process is analysed.
