Advanced Flow Modelling CFD Group Assignment-1 Objectives: To model and investigate using Computational Fluid Dynamics, the flow past a submarine. Apparatus: ANSYS Fluent /CFX will be used as currently available at UTS. Problem: The overall dimensions of the rectangular box will depend on the dimension of the Submarine. Or Figure 1: Schematic of the computational domain (You can use any design) Figure 1: Schematic of the computational domain (You can use any design) The fluid flowing through the rectangular domain is water, with the following properties: Density = 1030 kg/m3, Dynamic viscosity = 1.002 mPa.s The boundary conditions for all the CFD models are: Inlet velocity, U= 15 m/s; 60 m/s; 100 m/s Outlet Pressure = 0, Velocity at walls = 0 m/s (no slip) Flow = Turbulent using default settings. Procedure and discussion points: M o oA O 00~ O . Create a geometry in DesignModeler/ Solidwroks/any CAD software Build an appropriate mesh for the This will necessitate to run the simulations and make a grid refinement study presenting the results for different grids for U= 100 m/s. Using the converged grid, for U = 100 m/s, check the iterative convergence. . Using the converged grid, run CFX/FLUENT for U = 15 m/s, 60 m/s, and 100 m/s. Chart the axial velocity profiles u(y) at the leading edge, at mid, at the trailing position of the submarine and discuss your results. . Plot the velocity contours for U = 15 m/s, 60 m/s, and 100 m/s and discuss the flow . Plot the velocity vector for U = 15 m/s, 60 m/s, and 100 m/s and discuss . Plot the velocity streamline for all cases. . Plot the turbulence kinetic energy for all cases. . Plot the pressure contour for U= 15 m/s, 60 m/s, and 100 m/s and discuss your 11. 12. Calculate the drag and lift coefficient for U = 15 m/s, 60 m/s, and 100 m/s and plot the results. Verify your results with the existing Submission: A written report is to be submitted including a short introduction and conclusion (at least one page long for each). The report should contain a discussion of the points bolded above with evidence to support the discussion together with relevant figures such as figures illustrating the mesh or element distribution, plots of the velocity profiles, contour plots, etc
