Meaning of Chvorinov's rule | Babel Free

Definitions

An empirical formula used to calculate the solidification time of cast metal. The rule states that t=B(V/A)ⁿ, where t is the solidification time, B is a constant whose value depends on the material properties of the cast metal, V is the volume of the cast, A is the surface area of the cast that contacts the mold, and n is a constant that is usually around 1.5 to 2.

Examples

“Using Chvorinov's rule, we estimate the solidification time (t#95;s) of the liquid U metal, which can be determined by the volume of the molten alloy V (~ 4856 mm³), the surface area of the molten alloy A (~ 4311 mm²), the shape constant B [s/mm²], and the scaling parameter n (typically, n#61;2), as follows: […]”
