6 FAQs about [Energy storage ejection]
What is the ejection behavior of the freezing droplet on SES?
The ejection behavior of the freezing droplet on SES results from a two-stage energy conversion process consisting of energy storage (stage I) and energy release (stage II).
How fast does a pillar eject a droplet?
By recording the ejection process at 10,000 frames per second (fps), we found that the compressed spring-like pillar rapidly bounces up within 0.2 ms, which probably gives rise to sufficient force and energy for freezing droplet ejection (Fig. 2b).
Why does the ejection trajectory randomly deviate from the vertical direction?
The ejection trajectory randomly deviates from the vertical direction, which is mainly attributed to the non-perfectly symmetrical geometry and freezing process of the droplet in practice. Such a non-vertical trajectory enables the droplet to escape from the surface rather than return to the original launching site.
How do spring-like pillars eject freezing droplets?
The spring-like pillars can store the work done by the seconds-long volume expansion of freezing droplets as elastic energy and then rapidly release it as kinetic energy within milliseconds. The three-orders-of-magnitude reduction in timescales leads to sufficient kinetic energy to drive freezing droplet ejection.
How do you calculate kinetic energy gained by freezing droplet ejection?
As a result, the kinetic energy gained by the freezing droplet for ejection is calculated as Ek = ξEe – Es.
Is direct contact thermal energy storage based on jet breakup possible?
In this paper, a novel direct contact thermal energy storage concept based on jet breakup was proposed and studied. According to the experimental results, the following conclusions can be drawn:
