| Summary: | 碩士 === 國立中山大學 === 機械工程研究所 === 84 === The formation of primary and second dendrites from solving
axisymmetric energy and concentration equations in the solid
and liquid are investigated. A boundary element method can be
conveniently used to determine strong deformation of the solid-
liquid interface. Applying Mullins and Sekerka's mo-
phological criterion whose temperature and concentration
gradients , wavelength, and normal velocity along the inter-
face at any instant time are obtained from conservation
equation provides a clear understanding of the primary and
second dendrites during solidfication
