Comparison between Conduction and Convection Effects on Self
... cantilevers. The change in operating medium from h = 0 to h = 1,000 W/m2·°C results in temperature decrease in both cantilevers. The decrease is, however, more pronounced in Si/SiO2 cantilevers. This can be explained by the relatively higher temperature gradient existing for convective heat loss in ...

Heat Transfer
... 1.4 Convection Convection heat transfer occurs both due to molecular motion and bulk fluid motion. Convective heat transfer may be categorised into two forms according to the nature of the flow: natural Convection and forced convection. In natural of ‘free’ convection, the fluid motion is driven by ...
