A study on numerical problems of a coupled modelling of regional water balance and anthropogenic landcover change

This thesis describes the approaches applied to attempt to solve the numerical problems of the regional atmospheric model incorporated in the coupled modelling of regional water balance and anthropogenic land cover change in Amazon basin. For computational efficiency, the previous atmospheric model is evaluated at monthly scale. In order to cope...

A stable pressure-correction algorithm for low-speed turbulent combustion simulations

To perform accurate LES-calculations of low Mach number flows with non-premixed combustion, an efficient, robust and accurate algorithm is needed. So-called pressure-correction methods are efficient algorithms for this purpose. Those methods are well elaborated for flows with constant density. However, in non-premixed combustion simulations, the...
