Recent trends in mechanical micropumps and their applications: A review

In recent decades, several factors such as environmental protection, fossil fuel scarcity, climate change and pollution have driven the research and development of a more clean and sustainable transport. In this context, several agencies and associations, such as the European Union H2020, the United States Council for Automotive Research (USCAR) and the United Nations Economic and Social Commission for Asia (UN ESCAP) have defined a set of quantitative and qualitative goals in terms of efficiency, reliability, power losses, power density and economical costs to be met by next generation hybrid and full electric vehicle (HEV/EV) drive systems. As a consequence, the automotive electric drives (which consists of the electric machine, power converter and their cooling systems) of future vehicles have to overcome a number of technological challenges in order to comply with the aforementioned technical objectives. In this context, this paper presents, for each component of the electric drive, a comprehensive review of the state of the art, current technologies, future trends and enabling technologies that will make possible next generation HEV/EVs.

Next generation electric drives for HEV/EV propulsion systems: Technology, trends and challenges

In this study, Al2O3-water nanofluids flowing through a micro-scale T45-R type Tesla valve was investigated numerically. Both forward and reverse flows were investigated based on a verified numerical model. The effects of nanofluids flow rate, temperature, and nanoparticle volume fraction on fluid separation in the bifurcated section and the pressure drop characteristics were analyzed. It was found that most of the nanofluids flow into the straight channel of the bifurcated section when flowing forward, and into the arc channel when flowing reversely. The percentage of the main flow increases with flow rate, temperature, and nanoparticle volume fraction. Additionally, the jet flow from the arc channel leads to a larger pressure drop than forward flow. Finally, the diodicity was found most affected by flow rate, and a correlation used to predict the change in diodicity with the flow rate was proposed.
