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.
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.

Degrees of understanding of methods for derivation of balance equations, derivation of velocity distributions, calculation of energy balances in transportation of fluid through pipes and pipe fittings and infruence of fluid flow on heat and mass transport phenomena are evaluated. Score consists of 80% of results of the semester end examination and 20% of the exercises. Students must attend lectures because the results of exercise given in each lecture are reflected to the total score.
