What is fluid mechanics? • A branch of applied physics that is concerned with the motion of fluids and the forces associated with that motion • A branch of mechanics or physics that seeks to describe or explain the nature of physical phenomena that involve the flow of liquids or gases • Scope of fluid mechanics

Why process fluid mechanics? • Why chemical engineering? – Chemical engineering is what chemical engineers do. • Why transport phenomena? – Fluid mechanics (momentum transfer) – Heat transfer – Mass transfer

Why process fluid mechanics? • • • Fundamentals Industrial Modeling Design Engineering sense Insight for solving the physical problems

Why process fluid mechanics? • IT – – – Chemical vapor deposition (CVD) Hard disk drive Display (LCD) Battery Others • BT – Artificial organs – Blood flow, microcirculation, stenosis – Microfluidics, biomedical flow device, DNA chip

Why process fluid mechanics? • Cosmetics • Food – Ice cream, chocolate • Industrial – Extruder • Fundamentals – Pipe flow, particulate flow – Contraction flow – Flow around an obstacle Emphasis is on the problems associated with the process industries.
