Performance and design optimization of a low-cost solar organic Rankine cycle for remote power generation

Sylvain Quoilin, +3 more
- 01 May 2011 - 
TL;DR: In this article, the authors describe the design of a solar organic Rankine cycle being installed in Lesotho for rural electrification purpose, which consists of parabolic trough solar thermal collectors, a storages tank, and a small-scale ORC engine using scroll expanders.
Journal ArticleDOI

Buoyancy-driven heat transfer of water-based Al2O3 nanofluids in a rectangular cavity

Kyo Sik Hwang, +2 more
- 01 Sep 2007 - 
TL;DR: In this article, the effects of the volume fraction, the size of nanoparticles, and the average temperature of nanofluids on natural convective instability and heat transfer characteristics of water-based Al2O3 nanoparticles in a rectangular cavity heated from below are theoretically analyzed.
Journal ArticleDOI

Experimental validation of a prototype ejector designed to reduce throttling losses encountered in transcritical R744 system operation

Stefan Elbel, +1 more
- 01 May 2008 - 
TL;DR: Experiments confirmed that like in a conventional transcritical R744 system with expansion valve, the high-side pressure control integrated into the ejector could be used to maximize the system performance.

Techniques for cutting and coagulating tissue for ultrasonic surgical instruments

Shulte Dzhon B, +17 more
TL;DR: In this article, a plurality of input variables are applied to a multi-variable model to generate a multiview model output, where the multi-variate model output corresponds to an effect of the ultrasonic instrument on tissue.

Volumetric solar heating of nanofluids for direct vapor generation

George Ni, +10 more
- 01 Oct 2015 - 
TL;DR: In this article, the authors reported measured vapor generation efficiencies of 69% at solar concentrations of 10 sun using graphitized carbon black, carbon black and graphene suspended in water, representing a significant improvement in both transient and steady-state performance over previously reported results.
