Many thermal solar power plants use thermal oil as heat transfer fluid, and molten salts as thermal energy storage. Oil absorbs energy from sun light, and transfers it to a water-steam cycle across heat exchangers, to be converted into electric energy by means of a turbogenerator, or to be stored in a thermal energy storage system so that it can be later transferred to the water-steam cycle. Th...

At the smallest scale, hydropower or pico-hydro can be produced by utilizing water flow at piping system. This paper discusses about performance of a bulb-turbine in system using Computational Fluid Dynamic (CFD) method. study aims to analyze effect rate and speed on efficiency Solidworks Flow Simulation 2016. The propeller turbine design used this has 4 blades blade angle 200, static bulb with...

The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and enables the Michigan Department of Environmental Quality (DEQ) to maintain the state's authority over drinking water in the state. The DEQ also contracts with local health departments to maintain non-community programs in each county. Private water wells throughout the state are clearly the most troublesome for users and reg...

In this study, a cooling system for fusion reactor divertor that utilizes swirling flow generated downstream of multi-elbow piping was proposed, and fields the (triple elbow) were investigated using visualization experiment. Additionally, heat transfer experiment conducted under one-sided heating condition to simulate environment. The results revealed flux removed by in elbow exceeded critical ...

BACKGROUND Central dialysate fluid delivery systems (CDDS) are used by dialysis centers in Japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. In Japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

[1] Land drainage is common in peatlands. Artificially drained blanket peat catchments have been shown to have a significantly greater soil pipe density than intact catchments. This paper investigates the role of surface land drains in the enhancement of soil piping in blanket peats. The density of piping was found to significantly increase in a linear fashion with the age of the drainage. Thir...
