| dc.description.abstract | The aim of the study was to determine the combustion characteristics of liquid fuel mixture consisting of kerosene and vegetable cooking oil (VCO) in a swirl combustor. The swirl combustor is an effective combustor to improve the combustion process by supplying the tangential air to generate greater heat input. In this work, several air-fuel equivalence ratios were analyzed in several fuel blends to identify the combustion performance by obtaining the temperature distributions as a result of the combustion process. Two types of combustors were analyzed: a single air flow inlet and a dual air flow inlet. These air flow inlets were modelled in the SolidWorks which were then imported to the ANSYS software version 19.2 for the simulation purpose. The temperature profiles, T1, T2 and T3 were recorded and compared with both combustors operated on five different fuel mixtures. These fuel mixture were, 100% kerosene (100 Kerosene), 90%/10% kerosene-vegetable cooking oil (90/10 kerosene-vegetable cooking oil), 75%/25% kerosene-vegetable cooking oil (75/25 kerosene-vegetable cooking oil), 50%/50% kerosene-vegetable cooking oil (50/50 kerosene-vegetable cooking oil) and 25%/75% kerosene-vegetable cooking oil (25/75 kerosene-vegetable cooking oil). Also, the flame dynamics and temperature contour inside the combustors were analyzed and discussed at several ranges of fuel-air equivalence ratio. The simulations results showed that the dual air flow inlet combustor has better thermal performance as compared to the single air flow inlet. The temperature at the porous medium, T1 is higher than T2 and T3 for both combustors. In the dual-entrance air flow combustor, the temperature distributions for both T1 and T2 increased up to air flow rate, 50 LPM. However, the temperature reduced at the leanest mixture at 60 LPM. For every fuel blend, the exit temperature, T3 increased with decreasing of air flow rates. For a single-entrance air flow combustor, both T1 and T3 showed the highest values at 30 LPM while T2 patterns showed an increment at 60 LPM. The swirling air supplied into the system contribute to generate higher temperature. | en_US |
