The reaction between sulfur and iron under high pressure temperature (HPHT) was studied. Sulfur–iron models different levels were constructed. morphology formation mechanism of the reactants comprehensively analyzed by scanning electron microscopy, energy-dispersive spectroscopy–line scanning, metallographic Raman spectroscopy. results indicated that could significantly affect diffusion behavio...

This paper describes RHALE, a two and three-dimensional, multi-material, arbitrary Lagrangian-Eulerian (MMALE) shock physics code written in C++. RHALE is the successor to CTH, Sandia’s 3-D Eulerian shock physics code, and will be capable of solving problems that CTH cannot adequately address. RHALE employs a three step solution algorithm for the equations of motion: (1) a Lagrangian step capab...

We present an adaptive coupled level-set/volume-of-fluid (ACLSVOF) method for interfacial flow simulations on unstructured triangular grids. At each time step, we evolve both the level set function and the volume fraction. The level set function is evolved by solving the level set advection equation using a discontinuous Galerkin finite element method. The volume fraction advection is performed...

External electric fields were used to amplify thermal fluctuations at the interface between two thin liquid films. Similar to the results shown previously for the enhancement of fluctuations at the polymer/air interface, interfacial fluctuations having a well-defined wavelength were enhanced with a characteristic growth rate. A simple theoretical framework to describe the experimental observati...

Deep learning-based solutions for precision agriculture have recently achieved promising results. learning has been used to identify crop diseases at the initial stages of disease development in an effort create effective management systems. However, use deep and unmanned aerial system (UAS) imagery track spread diseases, diseased regions within cornfields, notify users with actionable informat...
