OPTIMUM CONTROL OF PROCESSES OF THERMO-MASS TRANSFER AT CONVECTION TO WOOD DRYING
153 KB
In article theoretical researches of the chamber for wood drying as object of management with the distributed parametres are considered. For the purpose of simplification the low temperature of drying of the lumber is considered as process of untied thermo-mass transfer, as it proceeds at constant temperature and head transfer to effect thermo-mass transfer can be neglected. Use a solution of the transfer equation standards for unlimited plate under the appropriate initial and boundary conditions. For a correct solution of the problem is introduced control function, which has the physical meaning of the flux density of the substance on the surface of the material. Also should be known: a condition of the agent of the drying, defining equilibrium humidity of wood, factor of carrying out of a moisture of wood and factor of an exchange of a moisture. During research the problem of optimum speed for infinite system of the ordinary differential equations is formulated at the set kind of restrictions on operating actions. The mathematics method receives an error estimation at the decision of the specified system of the differential equations.
