Dry Film

When a suspension dries, the suspending fluid evaporates, leaving behind a dry film composed of the suspended particles. We consider here the role of the particles softness on the drying process of a film with suspended fluid-filled elastic capsules.

Abstract An analysis is presented for the action of individual tire tread elements on polished sections of pavement covered by thin fluid films. Tread element flexibility, wheel slip, and time-dependent loading are incorporated. The effect of the lateral expansion of tread elements on groove closure is also studied.

Permeable Polymer

We study the drying of isolated channels initially filled with water moulded in a water-permeable polymer (polydimethylsiloxane, PDMS) by pervaporation, when placed in a dry atmosphere. Channel drying is monitored by tracking a meniscus, separating water from air, advancing within the channels. The role of two geometrical parameters, the channel width and the PDMS thickness, is investigated experimentally. All data show that drying displays a truncated exponential dynamics. A fully predictive analytical model, in excellent agreement with the data, is proposed to explain such a dynamics, by solving water diffusion both in the PDMS layer and in the gas inside the channel. This drying process is crucial in geological or biological systems, such as rock disintegration or the drying of plant leaves after cavitation and embolism formation.

Working Principle

This paper describes the working principle of the steam in the drying process,the structure of the steam heating system and the drainage system composition. Meantime the function and role of each component are described and studied how to build an efficient performance of the steam heating drying line.
