Study on gas migration law in large area goaf under coal spontaneous combustion environment
Meikuang Anquan, 2022 The air leakage flow field in large area goaf is complex, and the air leakage law is not clear. Once coal spontaneous combustion occurs, it will threaten the safety of the mine.

Buoyancy effects of a growing, isolated dendrite [PDF]
Journal of Crystal Growth, 1991 The buoyancy effect of a growing isolated dendrite on the solidification process in the undercooling liquid material was investigated by developing an analytic solution to the growth/convection problem in powers of a buoyancy parameter G. The solution depends on the Prandtl number P and the Stefan number S (undercooling) for the local velocity and ...

The Effect of Light on the Buoyancy of the Cuttlefish [PDF]
Journal of the Marine Biological Association of the United Kingdom, 1961 The behaviour of well fed cuttlefish is strikingly affected by light. When the light is bright they usually bury themselves in the gravel at the bottom of their tanks, whilst after twilight they come out of the gravel and swim around until dawn.Cuttlefish kept in complete darkness for one to two days usually become so buoyant that they are incapable of

The effects of buoyancy on sonoluminescing bubbles [PDF]
Acoustics Research Letters Online, 2000 Sonoluminescence from a single bubble was studied under microgravity and hypergravity environments to determine how buoyancy affects the light emission. The long-term objective of these experiments is to determine if buoyancy-related instabilities play a role in limiting the parameter space of single-bubble sonoluminescence. Understanding the parameter

The Magic of Buoyancy and Hydrostatics –Buoyancy and Effective Forces
Modern Applied Science, 2017 More than 2000 years after Archimedes formulated his famous law, there is today still some disagreement as to the physical understanding and actual acceptance and application of Archimedes’ Principle. This paper is prepared in the support of the full validity of Archimedes’ Principle, always calculating buoyancy as the weight of displaced fluid ...

Buoyancy and Marangoni effects on horizontal ribbon growth
Journal of Crystal Growth, 2022 Unsteady simulations of horizontal ribbon growth of silicon were performed that included both Marangoni and buoyancy effects. A chaotic flow was observed dominated by strong Marangoni-driven jets emerging near the local temperature minima on the free surface.

The Mediation Role of Meaning of Life in Relationship between Family Cohesion and Family Flexibility with Academic Buoyancy [PDF]
پژوهشنامه روانشناسی مثبت, 2019 The aim of this study was the assessment of mediating role of the meaning of life (including two subscales: Presence of Meaning and Search for Meaning) between family cohesion and family flexibility and academic buoyancy.
