The experiment of drying process of the fibrous material

Abstract

The article describes the experiment of water evaporation from fibrous material (cotton). The material is placed in the tube and hot air flows through (process of drying). Temperature of air is measured by thermocouple. The textile represents porous medium with certain amount of water (wet textile). Porous layer makes pressure drop when airflow starts. Properties of air (temperature, relative humidity) change during evaporation process. Values of pressure drop, temperature and humidity measured during experiment are used for set up of boundary condition, porous layer and evaporation model in Ansys Fluent 13.
