Modeling Drying Time of Dynamic Freeze Drying
Chemie Ingenieur Technik, 2018AbstractBei der dynamischen Gefriertrocknung wird die sich bildende Trockenschicht permanent abgerieben, was eine Steigerung der Trocknungsleistung mit sich bringt. Über die experimentelle Ermittlung der Wärmeübergangskoeffizienten in Abhängigkeit einiger Prozessparameter (Drehfrequenz, Beladung, Trocknungstemperatur) kann der Wärmeübergangskoeffizient

DRYING OF CARROTS. II. EVALUATION OF DRYING MODELS
Drying Technology, 1989ABSTRACT Three models of the carrot drying process. were evaluated. Shrinkage during the dehydration of carrots has been found to be important. Neglecting shrinkage would produce an underestimation of the test particle moisture content. A uniform drying contraction model describes the carrot shrinkage satisfactorily.

The causes of dry eye include lacrimal gland insufficiency, meibomian gland dysfunction, impairment of the neuronal innervation and environmental stress - all leading to irritation of the ocular surface. Several animal models have been developed to imitate different pathophysiologic mechanisms in the development of dry eye.

AbstractA theoretical model for drying of a thin gel film is presented. The model is based upon the premise that as solvent is removed from any portion of a gel structure which is permeable by the solvent, the structure shrinks locally to fill the voids left by the solvent.

Marangoni drying is a new ultra-clean drying process, which relies on surface-tension gradient forces, so-called Marangoni stresses. This method is of particular use in the semiconductor industry wherein obtaining ultra-clean surfaces is of paramount importance.

Suitable drying model for infrared drying of carrot
Journal of Food Engineering, 2006Abstract In this study, infrared drying characteristic of carrot was investigated in the temperature range of 50–80 °C. The strong influence of drying temperature on drying rate at early stage of drying was evident. Drying rate almost doubled when the drying temperature was increased from 50 to 80 °C.

We propose a simple theoretical model for the movement of a thin liquid film on a flat plate that is vertically withdrawn from a large liquid reservoir in the presence of a surface tension gradient. This problem is relevant to Marangoni drying—a technique that is used in the semiconductor industry for the purpose of water removal from wafers.

Although several mathematical models of primary drying have been developed over the years, with significant impact on the efficiency of process design, models of secondary drying have been confined to highly complex models. The simple-to-use Excel-based model developed here is, in essence, a series of steady state calculations of heat and mass transfer

Dry friction plays an important role in the dynamic behaviour of mechanical systems. Mechanical systems can come to rest in a finite time due to the presence of dry friction. Moreover, dry friction is also responsible for stick-slip vibrations, which occur for instance in brakes, wheel-rail contact and bowed instruments such as violins.
