New developments in the field of numerical methods have made it possible to carry out Direct Numerical Simulation (DNS) of combustion with unprecedented accuracy coupled with very high computational efficiency. A new technique based on the use of wavelet analysis has been used to develop a spatial discretisation scheme that offers a very high degree of local grid refinement a completely natural manner, without compromising the very high order of accuracy required in DNS, and without requiring special treatment in the refined areas.This makes the wavelet method especially valuable in combustion, where high resolution is required mainly in the region of the flame in order to resolve the fine structure resulting from the details of the chemistry and molecular diffusion. In previous DNS the ability to treat chemistry has been limited by the computational cost of providing the necessary degree of resolution throughout the domain, since there has been no method for high-accuracy adaptive grid refinement. The present proposal offers for the first time a means of carrying out combustion DNS on three dimensions with a high degree of realism in both turbulence and chemistry.In additional wavelet methods offer exciting new possibilities for data analysis and post-processing, due to their ability to select particular dynamic events for a stored dataset. This will enable selective post-processing to take place focusing on specific physical events.
