Air flow in a factory (boiler room)
For a factory the air flow distribution was investigated. How much air goes in and out? Where does it goes out? Velocity distribution plots and flow lines are giving a good indication of how the air is flowing within the factory. Design 25% pre-processing 25% Simulation 25% Post-processing...
NACA 0012 foil research & optimization
A Naca 0012 research & optimization was performed for the Aerospace Engineering program of the Aviation Emirates University in United Arab Emirates. With an educational purpose for the students of the University. Turbulent steady state simulations of the NACA 0012 foil were performed for different angles of attack, ranging from 0° to 25°. The Cd, Cl and Cp graphs are compared with benchmark data both experimental and theoretical. The laminar to turbulent transition is good noticable in the pressure distribution of the foil. Additional a laminar transient Direct Numerical Simulation (DNS) is provided to indicate the vortex shedding behind the airfoil for very low velocities. In this type of simulation the boundary layer is fully resolved and computed. A video of this simulation can be found here: https://youtu.be/uSUMC-1AQoA Optimization parameters allow for automatic shape optimization of the naca 0012 airfoil. As an example a high lift / low drag foil was created using a special CFD solver. The report includes the following subjects; Reynolds number range verification Theoretical background in the different turbulence models Grid independency study Benchmark data Validation results An additional mesh sensitivity report including the following subjects; Verification vs Validation Overall verification and validation methodology Examining spatial grid convergence Richardson extrapolation Mesh sensitivity study Research 20% Simulation 30% Optimization 15% Reporting...
Louver rain simulation
Rain particle simulations are executed to test the louvers for rain protection at different wind conditions from 0 m/s up to 2 m/s. The main question was: How much rain will penetrate through the openings of the louvers? A secondary question was: What is the air pressure loss through the louver? These questions were answered for multiple design configurations! Design 20% Pre-processing 30% Simulation 30% Post-processing...
