Course description and aims

Outline of the course: Heat and mass transport phenomena in chemical equipment depend significantly on characteristics of fluid flow. Equations of motion of fluid are derived from a view point of momentum transfer. Velocity distributions in various flow fields are obtained by means of the equations of motion.
Aims of the course: In this course, students learn the methods of solving the equations of motion for one dimensional steady and unsteady state problems. In addition, they also learn methods of calculation of mechanical energy loss by friction in transportation of fluid through pipes and pipe fittings based on energy balance equations. Furthermore, concepts of stream functions, velocity potentials and the boundary layer theory applied for two dimensional fluid flow fields are taken up as subjects.

Student learning outcomes

The target of this subject is to understand the similarity among momentum, heat and mass transport phenomena and to learn the basic knowledge and ways of thinking on methods for solving various problems related to momentum transport phenomena in chemical equipment.

Keywords

Momentum transport phenomena, Fluid flow, Velocity distribution, Fluid transportation, Stream function, Velocity potential, Boundary layer theory

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

In every lecture, slides in which the contents of the textbook were summarized are distributed to the students through the Tokyo Tech. OCW-i system and are used in class. An exercise problem is provided after every lecture. Due to the online class by Zoom, the answer should be submitted in pdf format through OCW-i by 17:00 on Friday of the same week as the class date.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
