The unsteady Euler and Navier-Stokes solutions have thousands of degrees of freedom. This means that the costs of unsteady flow studies are prohibitive. Schemes that retain the accuracy of the full ...

PACIFIC CITY, Ore. — Scott Burns, professor emeritus in geology at Portland State University, thought he had seen it all — until he saw a couple of photos of an extremely rare sand formation on the ...

The effect of scalariform perforation plates on the flow of water through plant vessels remains poorly understood. In this study, a new computational tool based on finite element method solutions to ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

This paper describes an evaluation of a series of commercially available natural gas fuel injectors, originally designed for heavy-duty diesel application, for use with hydrogen fuel in an electronic ...
