Cavitation in Pharmaceutical Manufacturing and Shipping
… at the University of Denver demonstrated that fluid cavitation can generate a large number of sub-visible protein particles in ultra clean formulations, but that mitigation can be achieved with fluid property manipulation. The goal of this research was to (1) assess the risk of cavitation under …

Microfluidic device for cytotoxicity screening
… process. We have developed a microfluidic device with internal structures that can evenly distribute cells across five chambers and requires only microliter volume of cell culturing media. In this study, we performed fluid dynamic simulations of different microfluidic designs with …

The consequences of gas slug ascent in a stratified magma on Strombolian eruption dynamics
… which slugs burst, controlling the eruptive dynamics. To date, little has been done to integrate this scenario into current models of volcanic eruptions and interpretation of geophysical signals. This study investigates slug ascent through a rheologically stratified magma column using …

Hierarchical Gaussian models for wind field estimation and path planning
… detailed offline measurements or computational fluid dynamic simulations, we extract empirical estimates of the mean and covariance functions. The associated covariance matrices are anisotropic and non-stationary, and capture interactions among the wind vectors at all points in a discretization …

An efficient heat engine for ocean thermal energy conversion
… boiling either pressurized ammonia-working-fluid in a closed cycle or vacuum flash boiling warm seawater in an open cycle, and then passing through a spinning turbine. Their efficiencies hover around 1% versus the possible 7% Carnot efficiency. This new thermal cycle has some similarity to …

Continuous synthesis of metal halide perovskite nanoparticles with sharp and stable emission
… modularity of the synthesis method, combining fluid dynamic simulations in a collaboration, bespoke 3D flow reactors, and on-line measurements (UV-vis absorbance and photoluminescence) reveals fundamental understanding about the growth of these perovskite nanomaterials, which in turn leads to …
