The diffusion of moisture and heat through textiles

Applications of Microwave Heating in Agricultural and Forestry Related Industries

“…The slower wave of the coupled heat and moisture system is always slower than either the isothermal diffusion constant for moisture or the constant vapour concentration diffusion constant for heat diffusion, whichever is less, but never by more than one half [12,13]. The faster wave is always many times faster than either of these independent diffusion constants.…”

“…The coupling between heat and moisture is well known but not very well understood [11]. Henry [12] first proposed the theory for simultaneous diffusion of heat and moisture in a textile package. Crank [13] later presented a more thorough development of Henry's work.…”

“…Relative dielectric heating and wood at fibre saturation moisture content, calculated using equation (12) and the dielectric properties of water and wood [48] Park, et al [54] studied the survival of microorganisms after heating in a conventional microwave oven. Kitchen sponges, scrubbing pads, and syringes were deliberately contaminated with wastewater and subsequently exposed to microwave radiation.…”

Therapeutic heat and cold in cardiac rehabilitation

“…Like human models, modeling a clothed body is also a challenge. Henry [100] modeled pieces of clothing by assuming a one dimensional flow, where heat flow occurs along the thickness of the fiber. Farnworth [101] builds on Henry's model by deriving a model for the transport of heat (conduction and radiation) and water vapor (diffusion) transport in a multi-layered clothing model.…”

Microwave Heating in Moist Materials

“…If a linear relationship between the moisture content of a material, the moisture vapour concentration in the air spaces in the material and the temperature is assumed (Henry, 1948;Crank, 1979), then:…”
