Improving efficiency of hydrogen cooling in cryogenic conditions is important for the wider applications energy systems. The approach investigated this study based on a Ranque-Hilsch vortex tube (RHVT) that generates temperature separation working fluid. simplicity RHVT also valuable characteristic In present work, novel shapes are computationally with goal to raise process. Specifically, smoot...
Abstract In this work, an experimental study on new series connection of two Ranque-Hilsch vortex tubes with generator materials, potential in seawater desalination was implemented, combined modification has not been studied open literature. Polycarbonate and Polyamide-Nylon 6 were tested compared as materials that enhance the heat transfer between air streams inside tube. Moreover, using prehe...
This paper investigates the relationship between product market competition (PMC) and innovation. A growth model is developed in which competition may increase the incremental profit from innovating; on the other hand, competition may also reduce innovation incentives for laggards. There are four key predictions. First, the relationship between product market competition (PMC) and innovation is...
