The shifting pattern of granulation visible on the solar surface represents rising and falling gas cells in the convection zone. The upwelling of gas in this zone, together with the Sun's rotation, amplifies and maintains the solar magnetic field. When the Sun was a pre-main-sequence star ,...
We conclude that the extremely rich and complicated dynamics of the upper convection zone reveal remarkable organization on the large scale, which can be correlated with the magnetic activity zones. 展开 关键词: Sun : activity Sun : helioseismology Sun : interior Sun : oscillations Sun : rotation...

What is the difference between the radiation zone and the convection zone of the Sun? Energy transfer by convection is primarily restricted to ___. What are the mechanisms of heat transfer? How are they distinguished from each other? What is meant when we say ...
The intensity of the non-equilibrium zone inside the cavity is increased with an increase in modified Rayleigh numberThe temperature fields are significantly affected by the effective thermal conductivity ratio than the scaled heat transfer coefficient of the fluid Zemach et al.

Leibfried and Ortjohann (1995) used smoke and light ash particles entrained in the streaming air to visualise circulating flow patterns and convective zone dynamics within two open cavities of different geometries. These insights were used in developing characteristic length definitions as well as ...
of a phase change zone. A fusion temperatureθfadjusts the strength and position of a phase change zone. The highest values ofNu¯are obtained whenα=1. An expansion in Hartmann numberHareduces the values ofNu¯. Adding more concentration of nanoparticles is improving the values ofNu¯....
1、The convection heat transfer coefficient of coolant within the grinding zone has been estimated using hydrodynamic and thermal modeling.(磨削区冷却液的热对流系数已由流体动力学和传热学模型估算得到。) 2、The outer layers form aconvection zonewhere the gas material transports energy primarily through ...
