Mathematical modeling of the isothermal impingement of liquid droplets in spraying processes
Gerardo Trapaga,Julian Szekely +1 more
TL;DR: In this article, a mathematical representation has been developed and computed results are presented describing the spreading of droplets impacting onto a solid substrate, which is of major practical interest in plasma spraying (PS) and in spray forming (SF) operations.
Journal ArticleDOI
Fluid flow, heat transfer, and solidification of molten metal droplets impinging on substrates: Comparison of numerical and experimental results
TL;DR: In this paper, a mathematical representation has been developed, and computed results are presented describing the spreading and solidification of droplets impacting onto a solid substrate, which is of major practical interest in plasma spraying and spray forming operations.
Journal ArticleDOI
A mathematical model of the spray deposition process
E. Gutierrez-Miravete,E. Gutierrez-Miravete,Enrique J. Lavernia,Gerardo Trapaga,Julian Szekely,Nicholas J. Grant +5 more
TL;DR: In this article, a mathematical model for the analysis of heat transfer during spray deposition is described, which is in two parts: the first part calculates the thermal histories of atomized droplets in flight, whereas the second part computes the transient temperature profiles inside the growing preform.
Journal ArticleDOI
Laminar-turbulent transition in an electromagnetically levitated droplet
TL;DR: In this article, a pair of co-rotating toroidal flow structures inside the spheroidal drop that undergo flow instabilities were observed. And the internal structure of the toroidal loops was used to develop a semi-empirical correlation for the onset of turbulence.
Journal ArticleDOI
Modeling of a DC electric arc furnace - Heat transfer from the arc
TL;DR: In this article, a mathematical model describing heat and fluid flow in an electric arc was developed and used to predict heat transfer from the arc to the steel bath in a DC Electric Arc Furnace.
