Course description and aims

Course overview: Students learn about tensor and vector analysis necessary for analyzing momentum transfer while learning to understand the meaning of and relationship between stress tensors and deformation rate tensors with regards to fluid deformations. In addition, by understanding the physical quantity of flux, which students dealt with at the undergraduate level as a scalar, instead as a vector and tensor, students learn about the derivation of balance equations, fundamental equations for transfer phenomena in a 3-dimensional field.
Purpose of course: Based on the above, students will understand velocity distribution, mechanical energy balance, stream functions, and velocity potentials for a variety of flow fields, analysis of 2-dimensional flows with boundary layer theory, performance evaluations of all sorts of devices operated mechanically, and a numerical analytical approach to transfer phenomena.

Student learning outcomes

It is necessary to make it clear the velocity distributions and relationship among fluid flow and transport phenomena, in order to design various equipment for separation and mixing. The purpose of this course is to acquire the advanced knowledge on the practical and complex fluid flow fields in chemical equipment and to learn the methods for evaluation of the performances of the equipment from a view point of transport phenomena.
