Rheological behavior of polyamide 11 with varying initial moisture content

Rheological and Physicochemical Properties of Honeys as a Function of Temperature, Concentration and Moisture Content

In this study the rheological and physicochemical properties of four types of honeys, two poly floral (Mountain, Forest) and two mono floral (Sunflower, Ivy), were investigated. Rheological characteristics of honeys were evaluated at different temperatures (10, 15, 20, 25 and 30ºC). All the honeys exhibited Newtonian behavior for shear rate in the range of 1.045-41.8 s-1. The viscosity of sampl...

Infiltration in cracking clay soils as affected by initial soil moisture content

Rheological behavior of microemulsions.

We study the stationary and transient behaviors of a microemulsion phase subjected to a shear flow. The system is described by a diffusion-convective equation that generalizes the usual Cahn-Hilliard equation. Nonlinear terms are treated in a self-consistent approximation. Shear, first and second normal stresses are calculated as momenta of the structure factor. Shear thinning is observed in st...

Determination of Moisture Content

Drying: moisture measurement at the end of drying is essential to follow up drying course and to decide whether it is achieved or not. On one hand, too long a drying course may have bad consequences for quality and food safety because of unexpected fermentations and mould growth. On the other hand, the next step in the process is storage. Also, drying to a too low moisture content can result in...

Mathematical Modelling of Non-Isothermal Moisture Transfer and Rheological Behavior in Cappilary-Porous Materials with Fractal Structure During Drying

The mathematical model of the distribution of deformation-relaxation and heat-mass fields in capillary-porous materials with fractal structure in the process of drying wood is regarded in the article. We used differential equations in partial derivatives of fractional order in description of this model. To describe the creep of wood fractional exponential Rabotnov’s function was used. The numer...
