Engineering materials are polycrystalline in nature, consisting of numerous single crystals interconnected through a three-dimensional interfacial network known as grain boundaries. Often essential in defining the performance and durability of materials, grain boundaries attract considerable attention during alloy development. Initially, we employ...

Numerical algorithms and computational tools are essential for managing and analyzing complex data processing tasks. With ever increasing availability of meta-data and parameter-driven simulations, the demand and the need for reliable and automated workflow frameworks to reproduce computational experiments has grown. In this work, we aim to develop...

The onset of morphological instabilities along a solidifying interface has a tendency to influence the microstructural characteristics of cast alloys. In the present study, the initiation as well as the mechanism of microstructural pattern formation is investigated by a quantitative phase-field approach. For energetically isotropic interfaces, we s...

Grain boundaries are potential sites for the development of morphological instabilities along a solidifying interface, and play an important role in the microstructural properties of cast alloys. In the present study, we employ a multiphase-field model to address the grain boundary grooving phenomenon under the cooperative effect of convection and...

In the present work, the growth competition of columnar dendrites is investigated in the presence of melt convection. By using a multiphase-field model, the microstructural evolution of unidirectionally solidified dendrites with different crystal orientations is addressed in detail. Generally, for converging bicrystal grains, the dendritic growth c...

In the present study, we employ a multiphase-field model based on the grand chemical potential formulation to simulate the microstructural transition in a binary FeSn monotectic alloy. In a directional solidification environment, we systematically investigate the formation of monotectic microstructures. At equilibrium monotectic composition, we obs...

In the present study, the morphological evolution of instabilities in a binary polycrystalline alloy is investigated under the influence of melt convection through phase-field simulations. In the absence of interfacial anisotropy, a grain boundary initiates and amplifies a convex ridge, which sequentially undergoes splitting and generates a random...

Contaminated groundwater remediation is becoming a crucial objective, as clean water scarcity is rapidly increasing around the world. Yet there are still many unanswered questions regarding the behaviour of the groundwater flow through subterranean sediment layers, one of them being the anisotropic hydraulic conductivity between layers. Data gained...
