Chemical Engineering Thermodynamics
化工热力学是化学工程专业的核心课程，将热力学原理应用于化工过程的分析与计算。内容包括流体的p-V-T关系与状态方程、纯物质与混合物的热力学性质计算、相平衡（汽液平衡、液液平衡、固液平衡）、化学平衡与反应进度、过程热力学分析（能量衡算、熵衡算、火用分析）、制冷与液化循环、动力循环等。学生将掌握化工过程中热力学性质的计算方法与过程能量分析技能。
Chemical Engineering Thermodynamics is a core course for chemical engineering majors, applying thermodynamic principles to chemical process analysis and calculation. Topics include fluid p-V-T relations and equations of state, thermodynamic property calculations for pure substances and mixtures, phase equilibrium (VLE, LLE, SLE), chemical equilibrium and reaction progress, process thermodynamic analysis (energy balance, entropy balance, exergy analysis), refrigeration and liquefaction cycles, and power cycles. Students master calculation methods for thermodynamic properties and process energy analysis skills.
学生需选择一个典型二元体系（如乙醇-水、苯-甲苯、甲醇-水等），设计实验方案测定不同组成下的汽液平衡数据。使用活度系数模型（Wilson方程、NRTL方程或UNIQUAC方程）对实验数据进行关联，回归模型参数，并比较不同模型的拟合精度。绘制温度-组成图与x-y图，验证热力学一致性，提交完整的实验报告与数据处理结果。
Students select a typical binary system (ethanol-water, benzene-toluene, methanol-water, etc.), design an experiment to measure VLE data at different compositions. Correlate experimental data using activity coefficient models (Wilson, NRTL, or UNIQUAC), regress model parameters, and compare fitting accuracy of different models. Plot temperature-composition and x-y diagrams, verify thermodynamic consistency, and submit a complete experimental report with data processing results.
