Coupled heat transfer, fluid flow and solidification kinetics for laser additive manufacturing applications

Author: Khomenko, MD ; Makoana, Nkutwane W ; Pityana, Sisa L ; Mirzade, FKH Date: Jul 2021 A new coupled heat transfer and solidification kinetics model is developed for the optimization of microstructure during laser additive manufacturing applications. The Johnson–Mehl–Avrami–Kolmogorov equation is applied in a self-consistent ... Read more
Empirical parameter identification for a hybrid thermal model of a high-speed permanent magnet synchronous machine

Author: Grobler, AJ ; Holm, Stanley R ; Van Schoor, G Date: 2017 An accurate thermal model will commonly require empirical parameter identification, specifically for the convection coefficients and interface resistances. A high-speed permanent magnet synchronous machine test platform, equipped with various ... Read more
Shape rheocasting of unmodified Al-Si binary eutectic

Author: Curle, UA ; Möller, H ; Wilkins, JD Date: Feb 2011 It is demonstrated experimentally that by using the Council for Scientific and Industrial Research Rheo Casting system and high pressure die casting it is possible to semi-solid process and cast into a shape unmodified Al–Si binary eutectic ...

Simulating moist convection with a quasi-elastic sigma coordinate model

Author: Bopape, Mary-Jane M ; Engelbecht, F ; Randall, D Date: Oct 2012 As part of ongoing model development work being done at the CSIR, a model that can be used to study thunderstorms has been developed. In this case we are showing its application over the Western Pacific ocean in the tropics where observation ... Read more
