In order to understand the drying behavior of the droplet,an integrated model was proposed taking account of the coupling between diffusion coefficient and the mass fraction of solutions,the coupling between the mass fraction of solutions and the vapor pressure of droplet surface as well as the coupling between the variety of droplet diameter and heat and mass transmission.
为更清楚地了解液滴的干燥过程,文中综合考虑溶剂扩散系数与溶液质量分数,溶液质量分数与液滴表面蒸汽压和滴径变化与传热传质之间的耦合关系,建立了包含液滴内部径向热传导方程,液滴内部的传质方程及液滴质量变化方程的液滴蒸发的完整模型。
