WE REVISIT Kraichnan’s method for generating synthetic turbulence and address a mass-conservation
problem in the original and later variations of that method [1]. Subsequently, a …

• Experience in parallel computing using MPI.• Experience in pressure-projection methods:
Pressure poisson equation, boundary conditions.• Experience in analytical modeling of uid …

A turbulent flow field is characterized by velocity fluctuations in all directions and has an
infinite number of scales (degrees of freedom). Solving the NS equations for a turbulent flow is …

The use of low-cost air pollution sensors mounted on drones is an exciting new approach to
conduct affordable and highly resolved air quality measurements. However, the air flow …

The COVID-19 pandemic forced performing arts groups to cancel shows and entire seasons
due to safety concerns for the audience and performers. It is unclear to what extent aerosols …

Internal flow modeling is a requisite for obtaining critical parameters in the design and
fabrication of modern solid rocket motors. In this work, the analytical formulation of internal flows …

This comment aims at addressing a mass conservation issue in a paper published in the
physics of fluids. The paper [RH Kraichnan,“Diffusion by a random velocity field,” Phys. Fluids …

In this paper, Taylor’s incompressible and rotational flow in a porous channel with surface
mass addition is extended to account for arbitrary headwall injection. Our analysis considers …

This dissertation is concerned with the mathematical modeling of the flow in a porous
cylinder with a focus on applications to solid rocket motors. After discussing the historical …

The Uintah Software framework was developed to provide an environment for solving fluid-structure
interaction problems on structured adaptive grids on large-scale, long-running, data-…
