Enhanced visualisation of complex thermofluid data: Vertical and horizontal combined convection and microscale heat transfer cases [PDF]
, 2000 Copyright @ 2000 UITIn general, convective heat transfer is an 'n-dimensional' problem where n is well in excess of 3 for steady flows. Traditionally, the method of dimensional analysis results in a small number of dimensionless groups.
