摘要: This lecture aims to place again the mixed thermal convection in center of heat transfer and emphasize three issues that arise by this approach: (i) a clear definition reference temperature Boussinesq approximation; (ii) practical delimitation convective modes, which are forced (FC), (MC) natural (free) (NC); (iii) and, finally, uniform description assembly FC/MC/NC similarity framework. Two examples analyzed : plane annular channels, for analytical solutions available. They allow detailed illustration proposed answers above issues, permit define characteristic scales convection. The case nanochannels is also examined.
