Original abstract
Solidification and cooling of a casting, with the simultaneous heating of the mold, is a case of transient spatial heat and mass transfer. This pape introduces an original and universal numerical model of solidification, cooling and heating, of a one-to three dimensional stationary and transient temperature field in a system comprising the casting, the mold and its surraundings. The casting process is influences by the thermophysical properties of the metallic and non-metallic materials. Determining these properties is often more demanding then the actual calculation of the temperature field of the solidifying object.
Czech abstract
Tuhnutí a chladnutí odlitků je složitým případem přenosu tepla a hmoty. Je předložen univerzální numerický model tuhnutí, chladnutí a ohřevu v podobě 1 až 3 D pro stacionární i nestacionární teplotní pole systému zahrnujícího odlitek, formu a okolí. Je zdůrazněn význam správného stanovení termofyzikálních vlastností materiálů odlitku i formy.
