The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake performance of the engine. Exhaust manifold gasket Victorreinz. If the solution from the FLUENT @ CFD code cannot reproduce the actual performance of the manifold, this means that configuration for the taper distribution manifold is not optimum. The intake manifold was originally the plastic piece from an M50 (the straight-6 used in the 1992-95 E36). DESIGN MODELLING AND MESH GENERATION: Using a 3-D CAD designing software the modelling of the intake manifold was done for the CFD analysis. This is mainly because a manifold/log design will typically see higher then a 2:1 pressure ratio in the exhaust ( as high as 4:1 with some logs). depend on defining the problem. The task entails the following: 1. Turbo Manifold Designs A look at log, tubular, and twin-scroll manifolds. Previous intake manifolds did not provide balanced distribution of air flow among all cylinders. I think I used the third harmonic to get the length. Intake manifold pressure behaviour, during idling, can be described, as follows: The nearly closed throttle valve chokes the air flow from the atmosphere as the engine pumps air mass away from the intake manifold. Thus the intake runner length is measured from the intake valve seat to the intake runner bell mouth, and not from the end of the intake manifold. They produce incredible top-end horsepower, while retaining good throttle response. The problem I'm having is there seems to be a large variety of different, conflicting calculations for calculating runner length and plenum volumes. Manifold must produce and hold power to at least 9500 RPM and also must have a usable power band. And a 'drag racing' style single 4 manifold has too much plenum volume.
