Modeling the drying of polymer coatings
Soft Matter, 2022We model the drying process in thin polymer films and predict the concentration profile and the stress-evolution during drying. The predictions of the polymer concentration profile match well with measurements.

Microwave drying of paddy: Drying kinetics and modelling
Agricultural Research Journal, 2022Paddy PR121 variety was dried using microwave at 2450 MHz. The effects of power level (180 - 450 W), air flow rate (3 - 7 m/s) and exposure time (4 - 12 s) for different bed thickness (3 - 6 cm) levels on the moisture content (16- 12%, wb) were analysed by means of response surface methodology.

DRYING OF CARROTS. I. DRYING MODELS.
Drying Technology, 1989ABSTRACT Three models of different complexity are proposed to describe the falling rate period of the carrot drying process with shrinkage. A moving or fixed boundary problem as well as a constant or local moisture and temperature dependent effective diffusivity are considered.

Drying of foods: Evaluation of a drying model
Journal of Food Engineering, 1995Abstract The drying of potato slabs in air flow is analysed by the simultaneous numerical solution of the differential heat balance and diffusion equations for a shrinking body. A uniform temperature profile in the solid and temperature dependent diffusion coefficient is assumed.

Hydrodynamic model for drying emulsions
Physical Review E, 2015We present a hydrodynamic model for film formation in a dense oil-in-water emulsion under a unidirectional drying stress. Water flow through the plateau borders towards the drying end leads to the buildup of a pressure gradient. When the local pressure exceeds the critical disjoining pressure, the water films between droplets break and the droplets ...

Modern Modelling Methods in Drying
Transport in Porous Media, 2006Several modern modelling techniques are presented as tools for drying science and technology, namely pore networks, discrete element method and population balances. After first presenting results from their own research, the authors indicate what future contributions to a better understanding of the drying process at different levels—single porous ...

MODELING DRYING OF A COATED PAPER
International Journal of Modeling, Simulation, and Scientific Computing, 2013Drying of a coated paper is modeled and simulated. The paper sheet is assumed to form three zones, and each zone has its own drying mechanism. Coupling of energy and mass balances must be used in order to solve differential equations. The simulations are carried out in various drying conditions i.e., only hot air drying, only radiant drying, and mixed

Physical Review B, 1994
The basis of dry friction is discussed using an independent oscillator model with longitudinal motion. This sample system is treated both numerically and with analytical methods. At vanishing velocity a sliding dry friction force is calculated which is smaller than the pinning force.

Drying Technology, 2004
The drying of materials is often described by nonlinear diffusion equations. Up to now the only way to solve these equations is by numerical simulations. Recently an analytic solution has been proposed for the drying problem. Based on this solution a sharp drying front model is presented. Measured moisture profiles during drying and the drying curve of

Agricultural Water Management, 1984
A one-dimensional diffusion model of canopy drying applied to a Pinus radiata forest yielded evapotranspiration rates during canopy drying less than those observed. The discrepancy indicated either there was a substantially greater interchange between the above and within canopy airflow than calculated assuming local diffusion, or there was a reduction
