Moisture Transport in Silica Gel Particle Beds: I. Theoretical Study

Research output: NRELTechnical Report


Diffusion mechanisms of moisture within silica gel particles are investigated. It is found that for microporous silica gel surface diffusion is the dominant mechanism of moisture transport, while for macroporous silica gel both Knudsen and surface diffusion are important.
