Turbine Design for Low Heat Organic Rankine Cycle Power Generation using Renewable Energy Sources

Abstract

Abstract. In recent years, due to its feasibility and reliability, the organic rankine cycle has become a widespread concern and is the subject of research. In the organic rankine cycle system, the radial turbine component is a highly influential component of the high low performance resulting. This paper discusses the design of radial turbines for organic rankine cycle systems. The design stage consists of preliminary design and detail design with parametric methods on the working fluid R22 to determine the geometry and initial estimation of the performance of the radial turbine. After that, a numerical study of the fluid flow region in the radial turbine with R22 as the working fluid was performed. The analysis was performed using computational fluid dynamics of Autodesk Computational Fluid Dynamics Motion software on two models of real gas, k-epsilon and shear stress transport. From the results of this analysis, there is pressure, velocity and temperature distribution along the radial turbine blades and estimated performance under various operating conditions. Comparison between parametric and computational fluid dynamics analysis results show different performance. The difference is due to the computational fluid dynamics analysis already involving the real gas shear stress transport model.

Development of the Biogas-Energized Livestock Feed Making Machine for Breeders

“…The solution is by providing generators or power plants that use other renewable energy sources [16,17]. Then keep in mind the cleaning process and make a time schedule [13][14][15][16][17][18]. In addition, it is necessary to pay attention to the maintenance time of this equipment, hence it is more durable and is used longer [13][14][15][16][17][18].…”

“…Then keep in mind the cleaning process and make a time schedule [13][14][15][16][17][18]. In addition, it is necessary to pay attention to the maintenance time of this equipment, hence it is more durable and is used longer [13][14][15][16][17][18]. Moreover, because the required motor power at maximum conditions is 10.1 W, hence it can use motors that are available on the market with a power capacity of 50 W.…”

“…At this time, many equipment's or machines for making the livestock feed have been developed. Some of them have developed types of fish feed making machine [2][3][4][5][6][7], there are also those who develop types of chicken feed making machines [7][8][9][10], there are also those who develop types of cow feed making machines [11], there are also those who develop other types of livestock feed making machines [12][13][14][15][16], and some have even developed a kind of livestock feed drying machine using renewable energy [18,19]. Hence, the development of the machine types for making the livestock feed becomes a challenge and also a solution for breeder's communities in their efforts to improve their economy and prepare for facing increasingly fierce competition.…”

Design of Rotary Dryer for Sand Drying using Biomass Energy Sources

“…Currently, many researchers are conducting research to develop equipment that can be operated using electrical energy sourced from renewable energy. Among them are those who developed the Organic Rankine Cycle (ORC) turbine design, which is devoted to producing electrical energy from heat energy sources with a temperature of less than 100 ºC [12]. There are also researchers who develop drying machine equipment that can be operated using electrical energy generated from solar energy [13], and also develop livestock feed processing equipment that operates using electrical energy generated from biogas energy [14], and there are also researchers who develop equipment for moving goods that are operated using electrical energy generated from other renewable energy sources [15,16].…”

Renewable Energy Technologies for Economic Development

“…Survey to these hamlets then were conducted to collect data on the availability of renewable energy sources as well as leading economic sectors determined by construction of each I/O Tables for the chosen hamlet [6,7]. Appropriate renewable energy technologies then were selected to supply energy for the leading economic sector [8][9][10][11][12][13]. Later cash flow analysis were conducted to determine economic viability of the system recommended and adjusted using PEST analysis.…”
