VISUALIZATION OF SCALAR TRANSPORT IN NONREACTING AND REACTING JETS THROUGH A UNIFIED "HEATLINE" AND "MASSLINE" FORMULATION

A unified formulation for heatline and massline calculations is presented in terms of conserved scalars, such as the total enthalpy and elemental mass fractions. The formulation allows some special forms of nonhomogeneous terms in the conserved scalar transport equation. Expressions for heatlines and masslines in single-component and binary mixtures reported by previous studies are shown to be special cases of the general expressions derived …
