An Automatic Moisture Meter Using Radio Frequency Heating

Measurement + Control, 1968
In one manufacturing process ICI, Nobel Division it became necessary to measure the moisture content, around 60 per cent, of a hot, sticky solid. The normal laboratory method involved drying in an oven at 100°C for 16 hours, the lengthy time required ...

Direct measurement of axial momentum imparted by an electrothermal radiofrequency plasma micro-thruster

Frontiers in Physics, 2016
Gas flow heating using radio frequency plasmas offers the possibility of depositing power in the centre of the flow rather than on the outside, as is the case with electro-thermal systems where thermal wall losses lower efficiency.

Effect of freezing rate and comminution on dielectric properties of pork

Czech Journal of Food Sciences, 2013
The impact of comminution and the freezing rate on the dielectric properties (ε' and ε'') of meats measured at frequencies used for cooking, i.e. radio frequency, RF (27.12 MHz), and microwave, MW (915 and 2450 MHz), were evaluated. The temperature rises

Average Heating Rate of Hot Atmospheres in Distant Clusters by Radio AGN: Evidence for Continuous AGN Heating

, 2011
We examine atmospheric heating by radio active galactic nuclei (AGN) in distant X-ray clusters by cross correlating clusters selected from the 400 Square Degree (400SD) X-ray Cluster survey with radio sources in the NRAO VLA Sky Survey.
