Résumé

Functions are directly defined in terms of dimensionless governing equations or variables. Some basic characteristics of the functions are illustrated in detail. The consistency of the formulations is especially addressed when dealing with conjugate convection-conduction problem. The functions-lines are unified for both fluid and solid regions, and the diffusion coefficients of the function equations are invariant. The method has been used to visualize the heat and fluid flow structures for natural convection in air filled square cavity over a wide range of Ra= 1000 - 1000000, and those for conjugate natural convection heat conduction problem where the conduction effect of solid body on heat transfer is investigated.
