Topic Information

Dear Colleagues,

The development of geo-energy and the storage of carbon dioxide and hydrogen involve physical mechanisms such as fluid dynamics, thermodynamics and solid mechanics, etc. The governing equations are generally partial differential equations of parabolic, hyperbolic, or elliptic type. Analytical or semi-analytical methods are often used to solve situations which are based on ideal assumptions, typically computationally efficient. For practical or complex situations, numerical methods are widely used, and the work in numerical models is generally aimed at describing more complex mechanisms or using new discretization schemes or solver strategies to improve computational efficiency or accuracy. This Topic focuses on recent advances in analytical or numerical models in the field of geo-energy.

The investigation of a Brownian particle subjected to an AC force that diffuses within a T-shaped chamber was conducted. This T-shaped chamber is composed of a strip cavity and a trapezoidal cavity positioned below it. The interplay between the AC force and asymmetric geometry creates a spatially bistable potential perpendicular to the AC force. With the assistance of noise, the particles can transition between two stable states and oscillate along the AC force at corresponding amplitudes at every spatially stable state. The asymmetric geometry facilitates the trapezoid cavity’s ability to more easily trap the Brownian particle than the upper strip cavity in the weak noise limit. Our observations reveal that proper noise can ensure the particle’s efficient trapping within the upper strip cavity and synchronization with the AC force, indicating the occurrence of geometric stochastic resonance. The T-shaped chamber serves as a simplified model, aiding in the further understanding of geometric stochastic resonance induced by irregular geometries and enabling the manipulation of microscopic particles in various small-scale systems.
