The Hybrid Numerical Model of Heat and Mass Transfer in Domain of Casting

In the paper the numerical model of solidification and segregation processes proceeding in the casting domain is discussed. The thermal processes described by the Fourier equation and the adequate physical, geometrical and boundary-initial conditions are simulated using the control volume method, while the segregation model bases on the collocation method described in (1). The coupling of the both algorithms results from the solidification rate (the heat transfer model) and changing solidification point (the segregation one). In the final part of the paper the example of numerical realization is shown.
