| Description:
| Aims: To introduce: 1) the underlying phenomena, design methods and principles of heat exhangers, and 2) boundary layer theory. 3) Compressible flow. Learning Outcomes: After successfully completing this unit students should be able to: * Develop heat transfer correlations for natural and forced convection. * Calculate natural and forced heat transfer coefficients. * Develop correlations for condensation at vertical and horizontal surfaces. * Calculate condensation coefficient. * Perform outline design calculations for shell, plate and spiral heat exhangers. * Appreciate different types of condenser and reboilers and their application. * Apply heat transfer theory to the design of embroilers and condensers. * Apply Reynold's analogy, film model and j-factor analogy to fluid flows. * Apply the continuity and the momentum equation to moving fluids. * Apply laminar boundary theory to moving fluids. * Describe compressible flow phenomena. Skills: Analysis and problem solving (taught/facilitated and assessed). Content: * Natural convection & forced convection, including dimensional analysis and correlations for heat transfer. * Heat losses from pipes. * Heat exchanger effectiveness - NTU relations. * Heat transfer from boiling liquids. * Dropwise and film condensation. * Heat exchanger selection and design, including various single phase units. * Introduction to boundary layer flow: definition of boundary layer thickness, simple form of the momentum equation and approximate solution for laminar and turbulent boundary layers. * Separation and wake formation. * Shocks and supersonic flow. * Models and mechanisms; Reynold's and film models, j-factor analogy. |
