Abstract | Multiple Mapping Conditioning (MMC) uses a mathematical reference space to provide an alternative dimension for modelling the turbulent transport that mixes parcels of fluid. Conceptualising this process is challenging when relying on the mathematics of the governing equations. This article presents the physical bases underlying the mathematics. The geometric processes used to create maps of the Earth are used as analogies for how combustion systems are modelled. Direct Numerical Simulations (DNS) are used to visualise how the 3-D turbulent distortions of non-premixed scalar fields can be represented by the 1-D mixture fraction. How the mixture fraction can be mapped to a reference variable is described, concluding with the processes used to apply the different methods of MMC to the modelling of turbulent combustion systems. |
