It is a model of the drying non-viscous extended droplet specified by the non-thermal diffusivity. For the construction of self-simulated solutions, a transition to the Riemann invariants is performed. Self-simulated solutions are functions of time and position determining the drop height, the mass-transfer rate and the heat flow averaged over the drop thickness. The found self-simulated solutions are classified on the basis of the behavior of the function that describes the drop height under the evaporation-condensation. The domains of applicability of various self-simulated solutions to the simulation of different situations of drying drops and films are identified.</p></abstract><trans-abstract xml:lang="ru"><p>В работе получены три типа автомодельных замен для задачи тепловой конвекции, осредненной по тонкому слою испаряющейся жидкости и являющейся моделью высыхания невязкой, нетемпературопроводной протяженной капли. Для построения автомодельных решений в работе выполнен переход к инвариантам Римана. Автомодельные решения представляют собой функции времени и координаты, определяющие высоту капли, а также скорость массопереноса и тепловой поток, осредненные по толщине капли. Осуществлена классификация найденных автомодельных решений на основании поведения функции, описывающей высоту капли в процессе испарения-конденсации. Выявлена область применимости различных автомодельных решений к моделированию различных ситуаций высыхания капель и пленок.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическая модель</kwd><kwd>автомодельные решения</kwd><kwd>капля</kwd><kwd>испарение-конденсация</kwd><kwd>mathematical model</kwd><kwd>self-simulated solutions</kwd><kwd>drop</kwd><kwd>evaporation- condensation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гольбрайх, Е.
