Abstract: | Convectional and sedimentation dissipative patterns of Miso soup, one of the traditional Japanese soups, were observed in
a Miso soup bowl, a green tea Ochawan (cup), a glass cup, a large glass bowl, and a large watch glass. When Miso soup was
set in the substrates, the distorted Benard cells were soon observed after the initial irregular circulations, and the holes
grew large at the cross points of the neighboring three Benard cells. The global integrated flow direction of convections
at the liquid surface was from the center area toward the outside edge during the periods of formation of the distorted Benard
cells. Meanwhile, the reversal of the global flow direction, from outward to inward, at the liquid surface took place. Furthermore,
the inward flow at the surface, i.e., the outward flow at the bottom, was accompanied with the broad ring-like sedimentation
patterns. The most plausible kinetic scheme of the change in the convectional patterns is proposed in this work. |
