Abstract
Abstract With the development of carbon dioxide geological storage, the Ostwald ripening process in pores has attracted the attention of researchers due to its application to storage stability problems. However, this process is difficult to reproduce accurately in the laboratory due to the large mass transfer time scale. This article utilizes two theoretical models of gravity‐induced ripening to analyze the influence of the hypergravity field on the process. It is concluded that a decades‐long mass transfer process can be shortened to 10 days if the acceleration of gravity is increased by 1,000 times. Moreover, if the scaling laws are considered, a scaled hypergravity model can be used to reproduce long‐term and large‐scale geological phenomena in a short period, facilitating future research on the Ostwald ripening process in hypergravity centrifuges.
