Abstract

The atomization process plays a very important role because the success or failure of combustion in the combustion chamber is influenced by the size of the liquid fuel mist. The occurrence of good atomization from atomized is determined by the size of the fuel droplets and the size of the nozzle diameter. Reducing the droplet diameter can increase the velocity, which can affect the Reynolds number and cause turbulence effects. The effect of turbulence provides a vortex effect, which enhances the heat transfer process between hot air and fuel particles in the combustion chamber. In this research, the effect of fuel magnetization on droplet size is analyzed. The fuel used is E0, E10, E20, E30, and E100, all types of fuel are channeled through an electromagnetic field of 1500 Gauss. Next, the particle size was tested using a Particle Size Analyzer, Bettersize BeNano 90 Zeta. The result was a decrease in particle size of 8-27%. The particle size measured using the PSA (particle size analysis) tool and theoretical calculations is <10% different. Each tool has an accuracy limit for PSA with a maximum accuracy of around 5%. These results provide initial information that the fuel magnetization process can improve engine performance.

Abstract

The provision of food, energy supply, and the provision of information are The food provision, energy supply, and information delivery are controlled to improve people's welfare. In 2011, the national electricity production by PLN was 11% new and renewable energy. 6% hydropower and 5% geothermal. PLN plans the geothermal to be 13% and hydropower to be 6%. The availability of independent PhPP has been built by many communities. PhPP with a waterwheel drive provides a capacity of about 100 watts thus it is only enough for home lighting, whereas the hydro energy potential of the area is quite abundant. The development that has been carried out has several weaknesses; PhPP plump turbine type requires a high head which becomes a constraint for agricultural irrigation, in the other hand PhPP waterwheel type has low efficiency. The research was conducted to develop PhPP low head cross-flow turbine type, which is more efficient. The development begins with the experiment of the PhPP cross-flow turbine model to optimize the ratio of the diameter and width of the runner. A preliminary case study provides experimental results for a cross-flow turbine's torque and power parameters at a flow rate of 0.053 m3/s. Changes in the turbine diameter and width ratio are optimum at a runner width of 10 cm.
