Course description and aims

Chemical processes involve fluids flowing through equipment, which invariably involve heat transfer. Therefore, engineers and researchers who handle the chemical process need to understand fluid dynamics and heat transfer. In this lecture, the fundamentals of fluid dynamics (momentum transfer) and heat transfer will be studied. In the former, students learn about flow conditions, velocity distributions, and the energy required for fluid transport. In the latter, three heat transfer mechanisms are studied, and the heat transfer rate and temperature variation with respect to space and time are studied for each mechanism.

Student learning outcomes

The goal of this course is for students to understand the phenomena of momentum and heat transfer, to acquire the ability to estimate velocity and temperature distributions and their changes over time, and to acquire the ability to solve problems related to fluid dynamics and heat transfer when designing and operating chemical plants and other equipment.

Keywords

Momentum transfer, heat transfer (heat conduction, heat convection, radiation)

Competencies that will be developed

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

Class flow

This lecture will proceed in the order of understanding the phenomena of fluid flow and heat transfer.

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.
