A comparison has been made between the Townsend primary ionization coefficient, α, for dry air and for air with humidities typical of those in the atmosphere. α is defined as the number of new electrons produced by an electron per centimeter of drift in a field. A range of field/pressure ratios,E/p 0, of 40 to 100 V (cm torr)−1 was employed.

Nonstationary convective drying of raspberries, assisted by microwaves and ultrasound
Drying Technology, 2019This study was conducted to investigate the drying characteristics and quality of raspberries dried in non-stationary conditions. Seven drying programs were carried out, including convective (CV) drying as a reference.

High silicon self-diffusion coefficient in dry forsterite
Earth and Planetary Science Letters, 2012Silicon self-diffusion coefficients (DSi) in dry synthetic forsterite single crystals were measured at temperatures of 1600 and 1800 K, from ambient pressure up to 13 GPa using an ambient pressure furnace and Kawai-type multi-anvil apparatus. The water contents in the samples were carefully controlled at

Heat pump drying of grape pomace: Performance and product quality analysis
Drying Technology, 2019Grape is one of the most popular fruits and various types of grape have been cultivated by more than 100 countries around the World. The wine and juice industry produces large quantities of by-product, called grape pomace (GP) as an industrial waste and ...

Measurement of diffusion coefficients in dry anaerobic digestion media
Chemical Engineering Science, 2013Dry anaerobic digestion of solid wastes is now commonly used at the industrial scale. Dry solid content in waste material is usually higher than 15%. w/w in these processes most industrial technologies in dry modes are not mixed, or sometimes intermittently mixed. In these situations convective transfer is negligible and diffusive transfer predominates

The partial coefficient of heat transfer in a drying fluidized bed
Chemical Engineering Science, 1956Abstract The determination of the partial coefficient of heat transfer from air to a drying fluidized mass of silicagel is given. The data obtained can be correlated by means of the equation h = 1·31 ( R ) 0·76 . A comparison of the external and internal heat exchange in a fluidized mass is presented.

A method for the calculation of the heat transfer coefficient in potato drying
Journal of the Science of Food and Agriculture, 1993AbstractA method for the determination of the heat transfer coefficient was proposed for the first falling drying period of potato cubes. During this period, heat and mass transfer were considered as coupled phenomena. Temperature calculation inside the sample was performed using the macroscopic heat transfer balance.

Shrinkage Coefficient: Drying Microcrack Indicator
In order to investigate the material behaviour in reality (macro-level) during drying shrinkage at early age, the shrinkage coefficient (αsh) is determined in the laboratory at micro-level on specially prepared and dried (1 mm) thick cement paste specimens. Drying shrinkage experiments are performed in Environmental Scanning Electron Microscope (ESEM).openaire +1 more source
