Porous medium relative humidity
WebHeat transfer in porous media can be combined with moisture transport for applications within consumer electronics, ... The physics interface has also been improved to support supersaturation conditions that correspond to a relative humidity greater than one. This occurs when a hot stream saturated with water vapor is rapidly cooled down. WebFeb 19, 2024 · The local relative humidity values for case 2 are higher than those for case 1 with a larger vapor saturated region. The pressurized operation of case 2 enhances the hydration and conductivity of the membrane even at higher working temperatures. The water content is higher in the porous media than in the gas channels.
