| Description: | Aims: * To introduce the full Navier-Stokes equations and give the physical significance of each term in the equations. * To introduce the student to CFD techniques appropriate for practical engineering applications (the finite-volume method). * To introduce the student to the use of commercial CFD packages, the importance of validation and the need for caution in applying the underlying models for turbulent flow. Learning Outcomes: After taking this unit the student should be able to: * Use CFD codes to compute 2D flows and understand the physical significance of the solutions. * Compute rates of heat transfer and shear stress. * Set up viscous fluid flow and heat transfer problems using a commercial code (with regular and possibly body-fitted grids), and extract features of the computed solutions for interpretation and validation. Skills: Problem solving; IT; numeracy; working independently; written communication. Content: LAMINAR FLOW: Navier-Stokes equations and energy equations; physical significance of the terms. Discretisation and solution of the non-linear equations using the finite-volume method. Pressure-velocity coupling. Alternative mesh structures. TURBULENT FLOW: Introduction to computational models of turbulence. Application to the computation of developing boundary layers and recirculating flows. Other methods of simulation and limitations of the current generation of turbulence models. |
