Abstract

The performance of a microhydro turbine is influenced by several factors such as the design process and the environment. The Archimedes screw is chosen for its excellence in converting the kinetic energy of the flow into mechanical energy in low-flow conditions. This research aims to design the Archimedes screw, gearbox, and calculate the generated power. The design methodology includes turbine design, flow simulation, and stress simulation. Additionally, the gearbox is designed to optimize the resulting rotation. The design results indicate that a turbine with a diameter of 0.45 m can operate at an average speed of 4 m/s, resulting in a turbine rotation speed of 169 rpm and a power output of 5076 watts. By using a generator efficiency value of 95%, the power output generated by the generator is 4822 watts.

Abstract

Plate-type heat exchangers in the process industry are generally used for efficient heat transfer between two fluid streams. The number of plates used affects the performance of the heat exchanger. This study aims to determine the performance of the SH1 54-M10-50 plate type heat exchanger against the variation in the number of plates being used in the CS2 recovery process and the performance at the number of calculated plates and determine the effective number of plates in the plate type heat exchanger for the CS2 recovery process based on performance calculations and simulations. The research was conducted at PT Asia Pacific Rayon in Pangkalan Kerinci, Riau and the CAD-CAM Lab of the mechanical engineering department, Sam Ratulangi University Manado, from February to April 2024. The performance of the heat exchanger was determined by calculation and simulation. Simulation of plate-type heat exchanger performance using Solidworks software. The results show that with 40 plates, the hot fluid exit temperature is 69.31°C and the cold fluid exit temperature is 67.4°C, with a total pressure of 4.48 bar and 4.76 bar, respectively. The calculation results are similar to the simulation results with the largest difference being 2.6%. For 50 plates, the temperatures are 65.92°C and 58.55°C, with total pressures of 4.34 bar and 4.57 bar, respectively.

Abstract

ABSTRACT Human dependence on energy in this modern era is increasing day by day. Currently, the use of energy from non-renewable sources to meet energy needs is still quite high, namely 71%, while renewable energy is 29% (IEA, 2021). Even though the process of generating energy from non-renewable sources has a negative impact on the environment. Therefore, the utilization of renewable energy sources which are more environmentally friendly, must be maximized. To find out the energy generated from the desained model, a simulation through ANSYS is needed. In the simulation process with ANSYS, an additional program is needed to cover the characteristics of the piezoelectric and use the ACT extension, Piezo and MEMS extension. Based on the research that has been carried out, it can be concluded that for modeling rainfall with strong intensity, it is obtained that there is an electrical energy of 0,00024623 volt, a small energy conversion requires a supporting component to be used for household electrical energy.

Abstract

Water supply is a crucial factor for farmers in managing agricultural land, especially those relying on river water sources. The lower position of rivers and the considerable distance from the fields often pose challenges, making water pumps powered by electricity or fuel a common choice, despite their high operational costs. To address this issue, the utilization of renewable energy through the use of a spiral pump powered by a water wheel is proposed. The spiral pump is considered an environmentally friendly technology as it does not require electricity or fossil fuels. This study aims to analyze the head of a spiral pump based on the parameters of an undershot water wheel as preparation for the design of the spiral pump. In this study, a significant decrease in discharge value was observed from a head of 0.5 m up to a head of 3 m; in contrast, from a head of 3 m to 10 m, the discharge value decreased gradually. For small agricultural land or household needs, this spiral pump water wheel would be suitable at a maximum head of 5 m with a discharge value of 0.53 L/s. The results show a negative correlation between the head of the spiral pump and the discharge produced, where an increase in head results in a lower discharge.
