摘要

The results obtained by solving a set of problems of simulating hydraulic nonuniformity in a channel with a permeable wall are used to form a training set on which the neural network database is constructed; the database is designed to determine the pressure distribution along the linear dispensing channel with a one-sided outflow. The channels with one-sided outflow of a medium through a wall are used in heat exchangers and fuel systems of the collector type, which find widespread application in the stationary power equipment of transport, atomic, and aerospace industries. Among many widespread heat exchangers of the collector type, we can mention the boiler unit superheaters or the shell-and-tube heat exchangers, whose thermal hydraulics depends in many respects on hydraulic nonuniformity. As a case in point, we can call, for instance, drying installations with parallel chambers, gas-cleaning units equipped with multiple parallel-working filters, furnace units equipped with multiple pot heaters, ventilation installations, and branching manifolds. Also related to the heat exchange equipment is the cooling jacket of the liquid-propellant engine chamber: it is the zone where the intensive heat exchange with combustion products takes place; coolant heating in the cooling ducts results in increasing the heat content of fuel cooling components and decreasing the losses of engine specific impulse. In the design of heat exchanging collector-type units with the desired service properties, it is necessary to predict hydraulic nonuniformity of the medium distribution along the tube plate, cooling duct channels, and mixing elements of combustion chambers (CCs).
