2. Introduction ASME Venturi Design Decision Intake Manifold –Fluent and Flow Bench Analysis –Intake Tuning Method Project Schedule

3. Venturi Design: ASME Standard D35mm L135mm R148.125mm α121Degrees R272.5mm Dt20mm L36.67mm R3100mm α27Degrees R4100mm L535mm

4. Venturi Design: ProEngineer Rendering

5. Flow Bench Testing System Integration with Vanderbilt Wind Tunnel Materials: PVC pipe and wood Goal: Obtain empirical data –Venturi model comparison –Intake Manifold model comparison to CFD results

6. Flow Bench Testing

7. “No Nozzle Left Behind”

8. Intake System Design: Helmholtz Resonance Tuning Optimum tuning peak selection –10,000 rpm Determine optimum volume of velocity stacks Following determination of manifold geometry –Determine inertial wave charging –Determine Helmholtz Resonance peaks

9. Intake System Design: Helmholtz Methodology System Geometry Parameters : Throttle Body/Venturi –Throttle Body Inductance –Restrictor Outlet Diameter –Venturi Inductance Plenum –Plenum Length –Plenum Average Area Runners –Intake Manifold Runner Length –Intake Manifold Runner Area –Secondary Runner Inductance Ports –Intake Port Length –Intake Port Average Area Cylinders –Displacement per Cylinder –Engine Compression Ratio
