Natural convection is flow driven by gravitational forces due to density differences within the domain. These density differences are often due to heat transfer. Key steps in setting up a natural convection analysis: - 1. For higher accuracy, use of a low-Reynolds boundary layer model o...

Your natural convection is very high. Such high convection is only found in micro and nano channels. As far as the difference between fluent h and real h is concerned, there is no specific number. If you raise or lower your reference temperature, the difference that you are asking will cha...
4c). These qualitative behaviors are in accord with our observations from natural dune fields (Figs. 2a and 4c). For all conditions, numerical experiments show that dune migration rate (commonly called celerity) slows as dunes grow larger; while this behavior is a well known consequence of ...

Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. Convection that occurs naturally is called natural convection or free convection...
