Mathematical model of the thermal and humidity treatment processes in a flow apparatus

Abstract

The ability to disperse heat treatment material moving in-flow gas stream is known. Heat in a moving stream of gas is characterized by high intensity of heat transfer from the coolant gas to the material and back from the heated material to the cooling air. However, no reliable mathematical model that reproduces the dynamics of heat transfer in the objects with distributed parameters, can not determine the rational parameters and modes such plants, hampering the development of management system. To address this issue in the article the mathematical model of heat conditions pnevmachnoho grain carrier based rozpodilenosti parameters. The basis for the model selected heat balance equations that describe the processes of convective heat transfer tubes for the selected item. The equations that determine the distribution of the coolant temperature and grain by pneumatic tract length for any point in time. This novelty is the possibility of one equation to determine the actual transition process for distributed object. The result of the paper is set mathematical dependence of grain temperature changes in the coolant-flow and movement in pneumatic channel height and time. The resulting dynamic model of heat transfer grain from the coolant can be used for the development of process control heating, which significantly increase its effectiveness.
