As the crisis of fossil fuel became more concerning, mankind are focused on finding another potential choice as alternatives fuels for engine. Biodiesel is one of the potential alternative fuels that can be created from a variety of biomass sources. Fortunately, Malaysia is one of the ASEAN countries that focused on oil palm industry in Southeast Asia which produces a large amount of excess crude palm oil (CPO) for consumption in vast quantities apart from CPO being one of the world demands as top four leading vegetable oils. These studies were carried out by using a Computational Fluid Dynamics (CFD) to investigate the effect of different swirl velocity and variant of ambient temperature, ambient pressure and injection pressure on swirl air entrainment on crude palm oil biodiesel. Spray and swirler modelling in SOLIDWORK are incorporated into the ANSYS CFX 18.1 to investigate the simulation. The modelling of swirler added to the chamber to increase air-fuel mixture was designed which contained an adjusted inlet that was skewed to the right of an angle of 1° and resulted in the appearance of 'gate' at the end of the inlet. The boundary conditions were set and the parameter were varied to 80 MPa, 100 MPa, and 120 MPa of injection pressure, 4 MPa, 6 MPa and 8 MPa of ambient pressure, 850 K, 950 K and 1050 K of ambient temperature and 10 m/s, 19 m/s and 30 m/s of swirl velocity. The fuel used in this study is a blended of 10% crude palm oil and 90% biodiesel Data and results obtained from simulation were analyzed. It shows that high injection pressure increases the velocity and the spray penetration length while increasing the ambient temperature and ambient pressure reduces the velocity and spray penetration length. The formation of swirl is better at higher injection pressure and at the optimum swirl velocity which is 19 m/s. The findings would be beneficial to the other researchers in the automotive industry [ABSTRACT FROM AUTHOR] |
