Author(s) : HOSSAIN M. M., CLELAND D. J., CLELAND A. C.

Type of article: Article, IJR article

Summary

A new expression for a geometric factor for ellipsoid shapes is developed by applying semi-analytical solutions of phase-change problems with convective cooling at the surface. Testing against finite element predictions for prolate and oblate spheroids, showed that the new formula is more accurate than any alternative shape factor for practical ranges of conditions.
