Thermal-fluid modeling of the Missouri S&T reactor
<p>"Thermal-fluid modeling of the Missouri University of Science and Technology Reactor (MSTR) was carried out using a computational fluid dynamics code (CFD), STAR-CCM+. First, a three-dimensional parallel-plate model was developed, and the cosine-shaped heat flux was applied to the MSTR core. …

Viscoelastic Fluid Modeling for Geophysical Applications in an Eulerian Framework
… Classical approaches in geophysical viscoelastic modeling often favor Lagrangian or mixed Eulerian--Lagrangian frameworks, which can provide high physical fidelity at the cost of increased computational complexity. In this work, we develop viscoelastic models within a fully Eulerian framework, …

Multinozzle printheads for 3D printing of viscoelastic inks
A high-pressure microfluidic device for 3D extrusion printing of viscoelastic ink was developed. The device was machined out of poly(methylmethacrylate) (PMMA) using a 3-axis CNC mill and contains a bifurcating array of microchannels that split a single stream of ink into 64 streams of equal flow. …
