Year-round outdoor experiments on a multi-stage active solar still with different numbers of solar collectors

TL;DR: In this paper, the authors investigated the outdoor performance of a basin type multi-stage solar still as well as the effect of collector over basin area (CBA) ratio on the distillate production.
Journal ArticleDOI

Investigation of ultra-thin flattened heat pipes with sintered wick structure

TL;DR: In this paper, a bilateral arch-shaped sintered wick (BASSW) was proposed for the improvement of the ultra-thin heat pipes (UTHPs) by sintering at the middle of its copper container and the vapor flow channels are located on both sides.
Journal ArticleDOI

Characterization of HTPB-based solid fuel formulations: Performance, mechanical properties, and pollution

TL;DR: In this paper, the HTPB polymer has been taken as a baseline and characterized at laboratory level in terms of ballistic properties, mechanical testing, and thermochemical calculations, and a series of proprietary techniques to evaluate, on a relative grading, the quality of innovative solid fuels while visualizing at the same time their flame structure.

Comparing conservative and nonconservative tracers in karst and using them to estimate flow path geometry

TL;DR: In this paper, a controlled recharge event was conducted with multiple tracers in a karst aquifer in southeastern Minnesota, and data were collected at Freiheit Spring approximately 95m north of the sinkhole to monitor spring responses.

Numerical analysis of heat and energy recovery ventilators performance based on CFD for detailed design

TL;DR: In this article, a detailed numerical analysis of heat and membrane-based energy recovery ventilators (HRV/ERV) using computational fluid dynamics (CFD) was presented.
