As shown in the figure, by decreasing the HTF inlet temperature and Reynolds number to 338 K and 400, respectively, the charging time escalates by 5% and 12%. In contrast, the increase of 5 K and 800 in HTF inlet temperature and Reynolds number, respectively, leads to the 8% and 12% decline in the charging time of the proposed LHTES.

A revolution in flour milling was occurring in Britain between 1875 and 1900, which started in continental Europe and concerned the replacement of stone grinding with roller machinery. 64 This was driven in the main by a fashion for white flour, which roller mills could provide more effectively by milling in a series of stages, in contrast with ...

Most conventional CHNOS mass spectrometers are dual inlet machines that have both a sample and a standard inlet or introduction port. In such instruments, the ratios of the isotopes of interest (e.g., 13 C/ 12 C) in the sample gas are measured relative to the same ratios in a gaseous standard that is analyzed more-or-less simultaneously.

The differential pressure between the inlet and outlet of the mill (∆P mill) is an important process variable for the testing of grinding aids. ∆P mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ∆P mill indicates more internal circulations and more fines. As a re-sult of the ...
