Mathematical Model for Design Parameter Analysis to Improve the Performance of a Desiccant Wheel

A mathematical model for estimating the optimum design parameters of a desiccant wheel in order to reduce weight and size has been developed. Heat and mass transfer from both moist air and desiccant material were considered in this model. The design parameters were analyzed under the basic operating condition of simulation. Channel height, pitch, and length of the desiccant wheel were optimized, as well as other design parameters such as area ratio, aspect ratio, and porosity. Optimum design parameters of a desiccant wheel were estimated by a newly developed mathematical model in order to reduce weight and size. Factors influencing moisture removal like channel height, pitch, and length of the desiccant wheel were optimized, as well as other design parameters such as area ratio, aspect ratio, and porosity.
