Abstract

Every type of fluid to be transferred has specific characteristics such as viscosity, density, friction, and others, thus requiring the selection of the appropriate pump type. One of the factors influencing the performance of a centrifugal pump is the number of blades used. This research aims to explore the influence of the number of blades on a centrifugal pump used as a fluid transfer device for crude oil. The study was conducted using the Computational Fluid Dynamics (CFD) method. The analyzed variations of the number of blades included three options, namely centrifugal pumps with 12, 14, and 16 blades. Based on the simulation results conducted using Solidworks Research License 2021-2022 software, it was found that the centrifugal pump with 12 blades exhibited the most optimal performance. The simulation results show uniform flow and pressure around the mid-span plane of the 12-blade impeller. In the case of the 12-blade impeller, the flow thrown by the centrifugal force is concentrated in the middle of the channel towards the outlet, resulting in higher pressure and volume flow rates.

Abstract

Energy consumption of a building is one of the biggest sources of energy use today. Green Building Comitte Indonesia (GBCI) has launched a concept of energy consumption saving in a nationally standard building. Audit Building energy audit is the way to know how actual building energy consumption is and find alternative solution to decrease energy consumption in order to fulfill the energy saving building criteria. Two types of HVAC systems will be run in the EnergyPlus simulation, split AC and central AC. The previous research proved that central AC is better than split AC system for energy saving in the building with 20 floors. The simulation results show that by using a certain energy system, a more efficient energy system will be achieved and can still maintain the comfort of the room at a temperature of 24 °C and relative humidity according to the Green Building Indonesia standard reference.

Abstract

Currently, an influential factor contributing to thermal comfort home design is the incorporation of energy-efficient passive design principles. It is exemplified by strategic window placement, the utilization of thermally efficient materials, and effective insulation. It exerts a substantial influence on thermal comfort and electrical consumption. This paper examines the effect of building shape and window-to-wall ratio (WWR) on thermal comfort and lighting energy consumption in residential houses in tropical climates. The lighting electricity and the adaptive thermal discomfort hours of 30 different models of houses were obtained using OpenStudio and EnergyPlus simulation software. The models were developed for three building shapes (square, rectangle, and L-shaped), and each model was varied in five models of window-to-wall ratios. Results indicate that the square-shaped model with a WWR of 10% will provide the lowest energy consumption in thermal comfort had 420.45 kWh/m2. On the other side, the lowest energy consumption in lighting is the square-shaped model with a WWR of 50% had 507.95 kWh/m2. Thus, the recommendation is to use the square-shaped house that represents the most efficient air conditioning system while the other WWR set also produce the most natural luminaire. It is because the percentage of WWR increased will result in more energy consumption in air cooling but slightly lower energy consumption in lighting. However, when considering aesthetics and freshness, the WWR of the 50% model will offer a better deal.

Abstract

The demand for electrical energy is increasing. Electricity supply in Indonesia is not yet evenly distributed. Indonesia's electrification ratio is only 99.63%. Generally, areas that have not been electrified are rural areas. It is necessary to utilize water energy sources for power generation. This research was conducted with a simulation tool from a micro hydro power plant with a crossflow turbine. The use of this turbine is because it is easy in terms of cost and manufacturing. The research was given an input source from a pump with a double pump system and a single pump system. Each system is given a variation of 100%, 75% and 50% openings. Data collection time is carried out for 90 minutes on each system and opening. From the research results obtained current, voltage, and output power. In the double pump system with 100% opening is relatively greater than 75% and 50% opening in the same system and in the single pump system. The maximum output current obtained in this study is 0.09 amperes with a double pump system opening 100% and the minimum output value is 0.02 amperes in a single pump system opening 50%. The maximum output power obtained in this study was 1.81 watts with a 100% opening dual pump system and a minimum output value of 0.32 watts in a 50% opening single pump system. The maximum output voltage obtained was 21.5 volts at 50% opening of the dual pump system, and the minimum output voltage was 15.8 volts at 50% opening of the single pump system. A large discharge will provide a large current, voltage and power output because it is able to crush the turbine with a relatively large speed. Discharge will affect the pressure and flow that occurs in the pipe, because the amount of discharge will be linear with the amount of pressure. The use of double pumps will get high efficiency with a large discharge. The greatest efficiency occurs when the double pump system.
