Abstract

The paper develops a mathematical model of duct air heating process, as widely used in drying of different materials in the form of powder. In this work, a mathematical model of the duct air heating system containing resistive heating element has been developed for simulation study, by considering one dimensional forced convective heat transport phenomena. Then a Continuous Time (CT) model identification technique based on Instrumental Variation (IV) approach has been applied to the actual duct air heating process, in order to identify the model parameters. The model was intended to evaluate dynamic changes in outlet air temperature corresponds to changes in current through the heating coils, air flow velocity and ambient temperature. The proposed mathematical model has been validated by a set of simulated models obtained from the experimental data collected from the actual setup, involving duct air heating under open loop conditions. The obtained responses of the mathematical model as well as identified system were found to be closely correlated with the experimental responses.

风管采暖系统的建模仿真与验证

本文建立了广泛应用于粉状物料干燥的风管加热过程的数学模型。本文在考虑一维强制对流传热现象的基础上，建立了包含电阻式加热元件的风管加热系统的数学模型进行仿真研究。将基于仪器变分法的连续时间(CT)模型识别技术应用于实际风管加热过程，以识别模型参数。该模型旨在评估出口空气温度的动态变化对应于通过加热盘管的电流、空气流速和环境温度的变化。通过从实际装置中收集的实验数据获得的一组模拟模型，包括开环条件下的风管空气加热，验证了所提出的数学模型。得到的数学模型响应和识别系统的响应与实验响应密切相关。
