TY - JOUR TI - On zero-dimensional ocean dynamics AU - Wang Yan AU - Wang Qian JN - Thermal Science PY - 2020 VL - 24 IS - 4 SP - 2325 EP - 2329 PT - Article AB - How to study the effect of the Sun or the Moon's gravity on ocean motion? Of course, Newton's gravity should be considered. However, Newton's law considers the Earth as a 0-D point, the ocean motion inside of a 0-D point of the Earth is negative 3-D, and Newton's law becomes invalid in a negative space. In order to solve the problem, we divide the Earth into two parts, one part is the studied ocean, the other is the left Earth without the ocean. A mechanics model can be then established for the 0-D ocean dynamics.
