Transport Phenomena
传递现象是化学工程专业的核心课程，统一研究动量传递、热量传递和质量传递的基本规律。内容包括流体动力学（粘性流体流动、层流与湍流、边界层理论）、热量传递（导热、对流传热、辐射传热）、质量传递（分子扩散、对流传质、传质系数），以及三种传递过程之间的类比关系。学生将掌握传递过程的数学建模与求解方法，为后续单元操作课程奠定理论基础。
Transport Phenomena is a core course for chemical engineering majors, unified study of momentum, heat, and mass transfer fundamentals. Topics include fluid dynamics (viscous flow, laminar and turbulent flow, boundary layer theory), heat transfer (conduction, convection, radiation), mass transfer (molecular diffusion, convective mass transfer, mass transfer coefficients), and analogies among the three transport processes. Students master mathematical modeling and solution methods for transport processes, building a theoretical foundation for subsequent unit operations courses.
学生需对圆管内充分发展的湍流流动与对流传热过程进行数值模拟与分析。建立动量传递与热量传递的数学模型，运用无量纲分析方法推导准则关系式，计算不同雷诺数下的摩擦系数与努塞尔数，并与经典经验公式（如布拉修斯公式、迪图斯-贝尔特公式）进行对比验证。讨论流动参数对传热效果的影响，提交完整的建模、计算与分析报告。
Students perform numerical simulation and analysis of fully developed turbulent flow and convective heat transfer in circular tubes. Develop mathematical models for momentum and heat transfer, derive dimensionless correlations, calculate friction factors and Nusselt numbers at different Reynolds numbers, and compare with classical empirical formulas (Blasius, Dittus-Boelter). Discuss the effects of flow parameters on heat transfer performance. Submit a complete report with modeling, calculations, and analysis.
