Module Details

Students are trained in basic Unit Operations (Network of tubes, pumps, heat exchangers)

Students learn to work with computing methodology and a commercial software to design unit operation processes s learn design unit operation processes

Students learn to design heat exchangers and calculate friction losses in network of tubes

Students learn to work and co-operate in multidisciplinary teams to present their results in original reports

To attend the module the student is encouraged to refresh basic Fluid Mecanics and Heat Transfer conecpts.

Introduction, definitions and principles. Dimensional analysis. Fluid statics and applications. Fluid flow phenomena. Basic fluid flow equations: Mass balance, Differential and macroscopic momentum balances, Mechanical energy equation. Bernoulli equation corrections. Incompressible flow in pipes and channels. Shear stress and skin friction, friction coefficient. Laminar flow of Newtonian fluids. Velocity distribution in turbulent flow. Friction from changes in velocity or direction. Minor losses. Pipes fittings and pumps. Developed head. Suction lift and cavitation. Power consumption, pump characteristics. Heat transfer by conduction. Principles of heat flow in fluids. Typical heat exchange equipment. Energy Balances. Heat flux and heat transfer coefficients. Mean fluid temperature. Overall heat transfer coefficient, Logarithmic Mean Temperature Difference. Individual heat transfer coefficients and calculation of the overall heat transfer coefficient. Fouling factors. Heat transfer to fluids without phase change: forced convection in laminar and turbulent flow. Heat transfer equipment. Single pass and multi pass cell and tube heat exchangers.
