What Is The Definition Of Convection In Science
WebConvection in a magma chamber [ 10, 11] due to heating from below and cooling from above is a special case of natural convection called Rayleigh–Bernard (RB) convection [ 12 ]. For Rayleigh values higher than 1703, the conditions are thermally unstable and advection occurs.
