The steps to conducting CFD simulations in ANSYS CFX are a. Import geometry (static.x_t-available in week 8 ilearn page) b. Construct a suitable mesh c. Set up the CFD model that

requires the following steps: Setup General: Select solver as a steady state solution • • Models: Turn on energy equations and select viscous model (laminar or turbulence) • Add material properties i.e. water • Assign the boundary conditions, including two inlets and one outlet with the correct boundary conditions according to your student ID. Solution • Methods: Conduct the simulation using the correct flow regime (laminar/turbulent flow) • Solution: Set the relaxation factors and/or residuals (convergence criteria). • Initialisation: Initialise domain - flow field can be initialized with 0 m/s velocity • Report files and Report definitions: identify parameters, values, and plots that are required to be reposted. • Run calculation: Set-up time step, the maximum number of iterations per time step, number of time steps, and reposting intervals. The total physical time is given in each section. d. Conduct another simulation with a refined mesh. e. Conduct a validation study (suggestion: analytical solution to compare your numerical result) f. Check if the solution converges and physical models are correctly selected. g. Visualise and analyse the results.
