Abstract

Theoretically, the performance air filter is in accordance to the shape design of air filter, the size of the air filter and the type of material used. The shape design of the air filter is selected as a lens on this research study. The conical design such as Rezton is chosen as an existing design due to its performance and similar design when compared to the improvement design. The performance of conical filter is mostly considered the design of the funnel, an angle of stem and the dimensions of stem. Thus, these characteristics are required when designing this conical filter. The concept of C-shaped transition curve or also known as high profile curve is then proposed to overcome this issue. SolidWorks is the software used in designing the air filter profile either in existing or in improvement design models. The structural schemes such as linear static and fatigue analyses are applied to find out the structural applicability amongst the models in static mode. The resulted showed that when the Maximum Von Mises Stress and displacement are lower, consequently, the good value of safety factor is achieved. Furthermore, the COMSOL Multiphysics 4.2a is the dynamic package that used to analyze the models in dynamic purposes. As the results, for the same input velocity where initial velocity is 6 ms-1 , the velocity, pressure and viscosity for improvement design are 82.152 ms-1 , 7848.8 Pa and 3931.4 Pa.s whereas 79.794 ms-1 , 15366 Pa and 691.73 Pa.s for the existing design. It shows that, the improvement design produced the highest values of velocity and viscosity and due to that, the pressure of the improvement design can be reduced. Therefore, the C-shaped design gives good impacts in designing the high profile air filter which then suitable for the performance car.
