“…This is also done by Craster et al 77 where the spreading and retraction of evaporating droplets containing nanoparticles is studied with a thin film model that involves a structural disjoining pressure. There are some similarities to other models 54,55,57 where, however, the contact lines are kept pinned. Since moving contact lines are an intrinsic part of the solute deposition process that we study here, we do not refer any more to these other approaches.…”

“…3,22,30,53 Various reduced models have been developed that: relate the interaction between the contact line and the deposit that is formed, in terms of a pinning force and derive how this force depends on and scales with the experimental parameters; 22,26 develop evolution equations for the shape of an individual deposited ring; 3 study the time evolution assuming a permanently pinned contact line. [54][55][56][57] Hu and Larson 58 analytically obtain a flow field that is combined with Brownian dynamics simulations to study particle deposition. Warner et al 59 employs a thin film model similar to the one we present below to describe the dewetting of a film of a nanoparticle suspension.…”

“…However, only very few studies allow contact lines to move and are therefore, in principle, able to describe the dynamics of a periodic deposition process, i.e., the stick-slip character of the process [5,114,[116][117][118]. Many works focus on evaporating drops with a contact line that always remains pinned at its initial position [115,[119][120][121]. This implies that they are only able to describe how a deposit forms for a fixed drop base, even if fully dynamic long-wave models are employed.…”

“…В данной работе для расчета эволюции распределения частиц вещества внутри испа-ряющейся пленки коллоидного раствора, а также профиля свободной поверхности плен-ки предлагается физическая модель, базирующаяся на уравнении Навье-Стокса в прибли-жении The Lubrication approximation [6][7][8][9], законе сохранения растворителя и уравнении конвекции-диффузии. Пленка помещена на твердую гидрофильную горизонтальную под-ложку.…”
