摘      要：The drying of liquid droplets is a common phenomenon in daily life,and has long attracted special interest in scientific *** propose a simple model to quantify the shape evolution of drying *** model takes into account the friction constant between the contact line(CL)and the substrate,the capillary forces,and the evaporation *** typical evaporation processes observed in experiments,i.e.,the constant contact radius(CCR)and the constant contact angle(CCA),are demonstrated by the ***,the simple model shows complicated evaporation dynamics,for example,the CL first spreads and then recedes during *** models of no evaporation,CCR,and CCA cases are given,*** scaling law of the CL or the contact angle as a function of time obtained by analytical model is consistent with the full numerical model,and they are all subjected to experimental *** general model facilitates a quantitative understanding of the physical mechanism underlying the drying of liquid droplets.
