Drying Model and Moisture Diffusion Coefficient
Advanced Materials Research, 2012Varied values of moisture diffusivity estimated using Crankâs equation with different initial moisture content, equilibrium moisture content and sample thickness are often reported. However, a theoretical explanation to this phenomenon is not available to date.

The moisture diffusion coefficient of a shrinking clay on drying
The Chemical Engineering Journal, 1975Abstract Experimental measurements on Hyde clay (kaolinite-type clay) demonstrate the difficulties in obtaining accurate data from materials which shrink both longitudinally and circumferentially. The isothermal diffusion coefficient based on modified length has been derived from steady state drying experiments by using only data for a sample ...

This study uses a heat flux sensor and temperature probes to directly measure vial heat transfer coefficients (Kv) during primary and secondary drying stages of lyophilization. It is observed that Kv is 40-80% smaller during secondary drying than primary drying, and this value exhibits a weaker dependence on chamber pressure than in primary drying ...

Heat transfer coefficients for drying in pulsating flows
International Communications in Heat and Mass Transfer, 1998Pulsating flows generated by a Rijke type combustor are studied for drying of grains and food particles. It is assumed that the velocity fluctuations are the main factor in the enhancement of the drying process. The heat transfer coefficients for drying in vibrating beds are utilized to estimate the heat transfer coefficients of fixed beds in pulsating

Accurate measurement of dry friction coefficient using reciprocating tribometer
2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018A tribological test is adopted to estimate the kinetic friction coefficient of the material of interest according to the ASTM standard. Typically a number of replicate is necessary to take into account the observed casual variability of the measurand as well as a post-processing data treatment is recommended.
