Finite element modeling of coating formation and transient heat transfer in the electric arc spray process
TL;DR: In this article, simulation of the coating formation and analysis of the transient heat transfer were performed based on a newly developed finite element model, in which the dynamic stochastic multiple particles deposition characteristic of the process was taken into account.

Heat transfer of micro-droplet during free fall in drop tube
TL;DR: In this article, a numerical solution by finite difference method with implicit Euler scheme was used to obtain the temporal evolution of thermal information inside micro-droplet, including the temperature distribution, cooling rate, temperature difference and gradient.

Influence of ceramic particles and process parameters on residual stress of flame-sprayed Fe-based coatings
TL;DR: In this article, a series of Fe-based amorphous composite coatings, mixed with ceramic particles, are prepared by flame spraying water atomized powder The morphology, structure and mechanical properties are investigated by scanning electron microscopy, X-ray diffraction and micro- and nano-indenter, respectively The residual stress and influence of process parameters on residual stress, such as ceramic content, type and spraying distance, have been systematically studied.

Solidification of droplets on a cold surface
TL;DR: In this paper, a simple model of two-dimensional radial flow has been used, and the degree of flattening ξm of a droplet depends upon the Weber, Reynolds and Peclet numbers, and upon the freezing constant U, taken from the solution of a Stefan problem.

Interaction of Flows with the Crystal-Melt Interface
TL;DR: In this paper, the effect of morphological and double-diffusive instabilities during directional solidification on the interface of a phase melt and phase change interface is investigated, and various applications for melt-flow interactions with solid-liquid interface to engineering and welding are discussed.

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.
