Fluid Configuration

High-velocity jets of fluid are encountered in both natural and man-made settings. The geyser, the fireman's hose, and the rocket exhaust are notable examples. Study of the fluid mechanics literature reveals the axisymmetric fluid jet as a fundamental fluid configuration that is rich in physical features. It is the purpose of this paper to discuss a few basic, but important, aspects of the behaviour of a water jet and ways that they may be directly observed by the senses, without recourse to sophisticated measuring devices, to the benefit of science and engineering students of all ages. These are observations which may be readily performed in undergraduate laboratories or even as homework assignments.

The study of transport phenomena in disordered media is a subject of wide interdisciplinary concern, with many applications in fluid mechanics, condensed matter, life and environmental sciences as well. Flows through grossly irregular (porous) media is a specific fluid mechanical application of great practical value in applied science and engineering. It is arguably also one of the applications of choice of the LBE methods. The dual field–particle character of LBE shines brightly here: the particle-like nature of LBE (populations move along straight particle trajectories) permits a transparent treatment of grossly irregular geometries in terms of elementary mechanical events, such as mirror and bounce-back reflections. These assets were quickly recognized by researchers in the field, and still make of LBE (and eventually LGCA) an excellent numerical tool for flows in porous media, as it shall be discussed in this Chapter.

ABSTRACTThere is a need to expand the fundamental skills in science and engineering to include innovation & entrepreneurship (I&E) skills as core competencies. To better prepare the future Nanotechnology workforce, the University of Puerto Rico-Mayagüez Nanotechnology Center, broadened the educational content beyond traditional skills in science and engineering. The Center, offers a rich educational program for materials and nano scientists that aims to create the next generation of knowledgeable, experienced professionals, and successful entrepreneurs, who can develop value-added innovations that can spur economic growth and continue to impact the quality of life for society. Within the educational program an Entrepreneurship Education Co-Curricular Program (EEP) incorporates I&E training into the Materials Science, Nanotechnology, STEM (Science, Technology, Engineering, and Mathematics) faculty and student experiences. The EEP consists of a two-year series of workshops that seek to develop an entrepreneurial mindset, including five key topics: 1) Generation of Ideas, 2) Entrepreneurial Vision, 3) Early Assessment of Ideas, 4) Identification of Opportunities, and 5) Strategic Thinking. The EEP goals, target audience, and implementation strategy, is described with an evaluation tool to assess the program’s success in developing an entrepreneurial mindset.
