The optical part of the biochip was modelled and simulated to optimize the total light collection efficiency and the system response. The optimization elucidated some of the optical aspects of the biochip. A study evaluating the bioluminescence reaction kinetics was performed and revealed the interdependence between the detected bioluminescence and the physical parameters of the introduced toxin.

However, the increased detail provided by CFD models is paid for with greatly increased computational time, and thus performing extensive parametric studies with CFD may be prohibitively time consuming.

This includes information on such basic processes as enstrophy and strain production, geometrical statistics, the role of concentrated vorticity and strain, and the reduction of nonlinearity.

This is true of such basic processes as
