Fluids flowing in equipment used in chemical processes have velocity and temperature distributions that must be controlled. Therefore, process engineers are required to understand these fluid dynamics and heat transfer. In this lecture, students learn how to derive differential equations and analyze them for fluid dynamics and heat transfer. Based on this understanding, energy operation and design methods in chemical devices will be studied.
The goal of this course is for students to acquire a deep understanding of momentum and heat transfer phenomena, to acquire the ability to quantitatively estimate velocity and temperature distributions, to solve complex problems related to fluid dynamics and heat transfer when designing and operating chemical equipment, and to acquire the ability to design equipment to perform energy operations.
