一、引言 在工程实际问题中,广泛存在着流动和传热的耦全过程。不少作者对这类问题进行过研究。作者在一维无粘的物理模型下讨论了加热对流动规律的影响,提出了热阻力、热阻力系数和无量纲加热准则数等概念,基于守恒方程组的求解,建立了它们之间的解析关系式,且通过实验定性地验证了理论分析的正确性。但是,在许多工 I. INTRODUCTION In the practical problems of engineering, the coupling process of flow and heat transfer is widespread. Many authors have studied such issues. Based on the one-dimensional non-stick physical model, the author discussed the influence of heating on the flow pattern and proposed the concepts of thermal resistance, thermal resistance coefficient and dimensionless heating criterion. Based on solving the conservation equations, Relationship, and through the experiment qualitatively verify the correctness of the theoretical analysis. However, many workers
