Abstract

A heat exchanger is a device used to exchange or change the temperature of a fluid by exchanging heat with another fluid. One of the heat exchangers is a surface type condenser where the steam is separated from the cooling water, the steam is outside the pipes while the cooling water is in the pipes at PT. SOCIMAS. At PT. SOCIMAS, the condenser is part of the main cooling system which functions to condense steam into water and maintain the efficiency and work cycle of the turbine high. For this reason, this final project report focuses on condenser analysis. The results obtained from this final project are the value of the inner convection coefficient of 4056.6827 W/(m2.K) and the outer convection coefficient of 97414.18W/(m2.K) . value of heat transfer rate and effectiveness (ε) on the condenser PT. SOCIMAS obtained a heat transfer rate of 153.6001264 MW. While the effectiveness (ε), obtained 0.99571 % This shows that the condition of the condenser is quite good, because the steam can go to the condenser, so that the rate of heat transfer and the effectiveness of the condenser are able to condense the steam into liquid.

Abstract

This study investigates the performance of TiAlN/TiN PVD-coated carbide tools in high-speed, dry machining of AISI 1070 alloy steel. AISI 1070 is a high-carbon steel known for its exceptional hardness, making tool wear a significant challenge. The research focuses on evaluating tool wear, wear mechanisms, and optimal cutting parameters. Quantitative assessments of flank wear (VB) were conducted, alongside detailed Scanning Electron Microscopy (SEM) analyses to identify the primary wear mechanisms, such as abrasion and adhesion. The study determined that the optimal cutting conditions for minimal tool wear include a cutting speed of 231 m/min, a feed rate of 0.1 mm/rev, and a depth of cut of 1 mm. The TiAlN/TiN coatings significantly enhanced the tools' wear resistance and longevity, maintaining their cutting-edge sharpness under strenuous conditions. Additionally, the coatings effectively minimized the formation of white layers on the machined surface, preserving the mechanical properties and surface integrity of the alloy. These findings demonstrate the coatings' superiority in reducing friction and heat generation during high-speed machining. The study provides valuable insights for industrial applications, highlighting the potential of TiAlN/TiN-coated carbide tools to improve tool performance, operational efficiency, and overall productivity in high-speed machining environments.

Abstract

The turning process is one of the most widely used lathe machining techniques in manufacturing, involving the interaction between the machine tool, workpiece, and cutting tool. During cutting, friction between the chisel and the workpiece generates excessive heat, with most cutting energy converted into heat. This study examines the effect of cutting speed on temperature in chisels, chips, and ST41 carbon steel workpieces at various lathe speeds. Using an experimental method, cutting speeds of 260 RPM, 560 RPM, and 800 RPM were tested. Data collected included lathe rotation speed, specimen temperature, chisel temperature, chip temperature, cutting depth, and chip mass. Results show that temperature increases with cutting speed. At 260 RPM, the chisel temperature was 38.46°C, the workpiece 36.83°C, and the chip 36.21°C. At 800 RPM, the highest tool temperature was 65°C, the workpiece reached 62.33°C, and the chip 48.56°C. This indicates that higher cutting speeds generate more heat, making the turning process more thermally intensive.

Abstract

This study investigates the impact of buoy frame width on the stability response time of water motorbikes, focusing on their ability to regain equilibrium after tilting. Water motorbikes are innovative vehicles designed to navigate flood-prone areas where conventional motorcycles cannot operate effectively. To enhance stability, buoyant frames of varying widths—40 cm, 45 cm, and 50 cm—were tested at three initial tilt angles: 5°, 10°, and 15°. The research employed an experimental approach, utilizing digital inclinometers to measure tilt angles and stopwatches to record response times. Data analysis revealed that frame width significantly affects stability, with wider frames yielding faster response times. For instance, at a 5° tilt angle, the 50 cm frame achieved a response time of 3.12 seconds, compared to 4.84 seconds for the 40 cm frame. Similarly, wider frames consistently outperformed narrower configurations across all tested angles. ANOVA results confirmed the statistical significance of the findings, with p-values less than 0.05. The results demonstrate that increasing the width of buoy frames enhances the stability of water motorbikes, making them more efficient and reliable for use in flood-affected areas. These findings provide valuable insights into the design and optimization of water motorbikes, contributing to safer and more practical solutions for flood navigation.

Abstract

A Very rapid population growth has resulted in fossil energy being gradually depleted and environmental pollution getting worse. So far, burning fossil fuels has produced about 40% of global carbon dioxide (CO2) emissions, which are considered a major source of greenhouse gases. The Internal Combustion Engine (ICE) has become the main power source for cars, trucks, locomotives, and ships. In ordinary diesel engines, less than 45% of the fuel energy can be converted into useful work output from the crankshaft, and the remaining energy is largely lost through exhaust gases and jacket water. One way that can be done is to utilize the waste from the internal combustion engine (ICE). This method uses the Organic Rankine Cycle (ORC) system by utilizing the wasted heat generated by the Diesel engine when operating, through the engine coolant coming out of the engine gap (water jacket) to the radiator. In this study, the study focused on the exergy analysis of each component in the ORC system integrated in the diesel engine cooling unit which was simulated using Aspen Plus software. The analytical method used in this study is the exergy method with variations in ambient temperature of 20oC, 21oC, 22oC, 23oC, 24oC, 25oC, 26oC, 27 oC, and 28 oC using the working fluid R141B. The results showed that the greatest exergy destruction was found in the components of the pump, evaporator, and turbine.
