Transport of scalars by turbulent fluid motion is of fundamental importance and is encountered in applications such as pollutant formation, mass and heat transfer and chemical reactions. The physics of many of these applications is extremely complex and not well understood due to the intriguing complex topology of the fluid motions and scalar fields. In this paper, a new formulation is proposed to study the detailed topology of diffusing scalars and their relationship to the turbulent flow topology. Direct numerical simulations (DNS) are used to study those topologies in homogeneous isotropic turbulence, using an object-oriented code (Crespo 1994).
