| Abstract: | Equivalence for critical heat is one of the numerical treatment commonly used solving questions of solidification heat transfer. Many authors have investigated the equivalent object using various method. The paper develops an equivalent substantial derivative method that can simulate influence that critical heat on the temperature field accurately. The method is simple in computer implementation. The example shows that results are well coincided with those in pract ice. |
