Effects of matrix moisture on gas diffusion and flow in coal

Fuel, 2010
Abstract Gas production from coal is a complex process whereby gas, initially adsorbed in the coal matrix, desorbs and diffuses through the matrix into the cleat and eventually flows through the cleat system into a production well or a drainage borehole.

Estimation of Effective Moisture Diffusivity in Starchy Materials Following Hydrothermal Treatments

Defect and Diffusion Forum, 2011
Two hydrothermal treatment processes (DV-HMT and DIC treatment) were investigated on standard maize starch for three processing temperatures; 100, 110 and 120°C. The gravimetric change of starch powder during the treatment was analyzed by a simultaneous water diffusion and starch reaction model. The effective diffusivity coefficient (Deff) and reaction

Effect of Ultrasound on Effective Moisture Diffusivity: An Assessment by Numerical Method

Journal of Advanced Research in Numerical Heat Transfer
The experimental evidence has favored the application of ultrasound-assisted drying techniques on the dehydration of food material. Compared to traditional hot air drying, The shorter drying time in the ultrasound-assisted drying process can be explained by the enhancement of heat and mass transfer inside the product and the restraining of external ...

A Mathematical Model of Effective Moisture Diffusivity for Lychee Drying

International Conference on Crop Harvesting and Processing, 2013
The objectives of this research were to develop an effective moisture diffusivitymodel and to study the effect of drying air temperature on dried product quality. Thethin layer-drying model in spherical form was studied. Analytical method wasextensively used in the experimental estimation of effective moisture diffusivity.

Effects of Fibre Permeability on Moisture Diffusion Coefficients of Polymeric Composites

Polymers and Polymer Composites, 1993
A single fibre composite model reinforced with a permeable fibre is used to evaluate the moisture diffusion coefficient analytically. Due to the fibre permeability, absorption of moisture takes place through both the fibre and the matrix. The diffusion paths around the fibre, due to their curved nature, are generated using the cubic spline theory. The
