Gagarin Military-Air Academy”, Voronezh, Russian Federation, 2 Voronezh State Technical University, Voronezh, Russian Federation * borodkinstanislav@ya.ru На основе экспериментальных данных по газификации кислорода на установке СГУ-7КМ-У выполнена идентификация дифференциальной параметрической модели теплообмена в газификаторах закрытого типа. По результатам опорных опытов идентифицированы внешние параметры – мощность нагревателя, теплоемкость испарителя и производительность насоса. Внутренние параметры модели – числовые множители при коэффициентах теплоотдачи в кислороде, теплоносителе и окружающей среде – идентифицированы методом пассивной стратегии. Разработаны методики оптимизации работы газификатора по достижению заданного диапазона выходной температуры в стационарном и нестационарном режимах работы. Методики апробированы на примере газификационной установки СГУ-7КМ-У. This paper presents experimental data on oxygen gasification as performed on an SGU-7KM-U unit; data is used to find a differential parametric model of heat transfer in closed-loop gasification units. Reference experiments helped find the external parameters such as the heater power, the heat capacity of the evaporator, and the pumping rate. The internal parameters of the model, i.e., the numerical multipliers for coefficients of heat transfer in oxygen, coolant, and the environment, were identified by the passive strategy method. The paper further presents newly developed methods for optimizing the gasifier performance to reach the required range of output temperatures in steady-state and non-steady-state operation. The methods were tested on an SGU-7KM-U gasification unit.
