Experimental Check of Ivantsov Relation
|
|
|
|
|
Possible
reasons for deviation:
|
|
|
|
|
|
|
|
|
|
| • |
Proximity
of sidearms or other dendrites (especially at low DT)
|
|
| • |
Convection
driven by density change on solidification
|
|
|
| • |
Residual
natural convection in mg
|
|
|
| • |
Container size
effects
|
|
|
| • |
Non-axisymmetric deviations from Ivantsov solution

“… the diffusion field described by [the Ivantsov solution] is
|
|
|
based on a dendrite tip which is a parabolic body of
revolution,
|
|
which is true only near the tip itself.” [Glicksman
et al. (1995)]
