Analogy Teaching Exploration and Practice of Reactor Design through a Question in Life
Chemical Reaction Engineering is a basic subject which studies engineering problems through mathematic models.Reactor design is an important part.This work tried to introduce a common question in life—why shouldn't we gobble?In this regard,the mouth,stomach,and intestines of our bodies were analogized to batch reactor,continuous stirred-tank reactor,and plug flow reactor,respectively,to help students understand the structure and feature of reactors.Meanwhile,this question was converted into three quantitative questions in chemical reaction engineering to conduct the teaching on designing ideal reactors.Therefore,the mathematic models for designing the three reactors were established,followed by three relevant examples to quantitatively answer the proposed common question in life and close the loop of teaching activity.The analogy teaching based on a question in life could effectively elevate the interest of students,stimulate students'learning motivation,and lay a solid foundation for their further study on the concept of reactors in series.
