“…Referring to Chiong et al [20], swirl flow is generated by spiral rotation, with rotating vanes being applied to a flow by the component of the tangential velocity. According to Xi et al [2], the turbulence produced by swirl vanes would enhance the mixing of air and fuel, as evidenced by a drop in NO and an increase in CO2. In addition, the vortex intensity increased, which is supported by the study of Yilmaz et al [6], although the NOx emission did not change much with changes in CO2.…”

“…When Xi et al [2], Anacleto et al [4], Yilmaz et al [6], and Chiong et al [20] investigated swirling vanes on a turbine, in this work, we investigated a combustion engine with a carburetor fuel system. The finite element method was employed in the computation process as performed on Xi et al [2], [19].…”

“…The Venturi accelerates the flow and creates a pressure difference according to the principles of Bernoulli's theory, as well as a vacuum in the section, allowing the air and fuel flows to mix evenly. To improve engine performance, the amount of air-fuel mixture entering the combustion chamber must be increased, both quantitatively and qualitatively [1], [2].…”

“…Turbulent flow creates a more combustible mixture, which increases engine performance. Xi et al [2] noticed that swirling vanes improve turbulence and result in a more homogeneous mixture. Furthermore, numerous previous studies have reported the success of the application of swirling vanes.…”

Although the technology of fuel injection in motorcycles has reached ports and direct injection, motorcycles with carburetors are still used. In this research, the carburetor was modified by adding a swirling vane. This study is intended to provide an explanation regarding engine performance which includes torque, power, mileage, emissions, and engine oil temperature. The study begins with a review of the shape and flow characteristics of the swirling vane based on the largest flow according to previous studies. Then, a swirling vane is built and tested to ensure its optimal shape. The findings were compared with conventional carburetor-based engines that had not been treated. Experiments were also carried out on gasoline-ethanol to obtain optimal results and use them appropriately for alternative fuel applications. A comparison of data on torque, power, exhaust emissions, temperature, and mileage reveals that vehicles modified with swirling vanes have better performance. Furthermore, based on the results of gasoline-ethanol application tests, this design is only suitable for use up to E25.

“…Li et al – used the CFD-DEM coupling method to simulate and verify the movement characteristics of pulverized coal particles in swirl pneumatic conveying processes, mainly revealing the flow characteristics, velocity distribution, and resistance characteristics of pulverized coal particles, which can provide a reference and theoretical basis for the design of pulverized coal conveying pipelines. Tang et al , mainly studied the effects of swirl-vane angles and particle size on combustion and flow characteristics. Hirota et al studied the conveying characteristics of materials with three different densities in pipelines with varying inclinations, and it was found that density has a significant impact on the solid-phase friction coefficient.…”

According to the design and operational parameters of the cyclone liquid slag-discharging boiler, an experimental platform for the cyclone burner was designed and constructed in a cold state based on the principle of similarity. The experimental study investigated the effects of parameters, such as swirl-vane angles, coal concentration, operating parameters, and particle size, on the flow distribution and vertical riser resistance characteristics of the vertical cyclone burner. The results showed that there were differences in flow distribution among the cyclone burners, and the most uniform flow distribution was achieved when the swirl-vane angle of the primary air was 30°. The concentration of pulverized coal significantly influenced the pressure drop in the vertical ascending section, which increased with higher concentrations of pulverized coal. When the concentration of pulverized coal remains constant, the pipeline pressure drop is minimized at a primary air velocity of 7.5 m/s. As the secondary wind speed increased, the pressure drop consistently rose; when the secondary wind speed is 22 m/s, the pressure drop of the pipeline is the maximum; however, excessively high secondary wind speeds were found to be detrimental to the formation of an optimal aerodynamic field in the burner. Furthermore, when the pulverized coal concentration was held constant, materials with larger particle sizes exhibited the highest pressure drop. When the particle size increases from 50 to 150 μm, the pressure drop of the vertical riser segment also increases. Finally, based on the Barth additional pressure drop theory, the pressure drop formula of the vertical riser is fitted by a dimensional analysis method, and the correlation formula of the pressure drop test of gas–solid two-phase flow in the vertical riser is obtained.
