The rapidly increasing energy demand worldwide is directing countries towards sustainable and renewable energy sources. In this context, the evaluation of waste in energy production both reduces energy costs and contributes to environmental sustainability. Alternative fuels, especially oils obtained from waste plastics, are among the remarkable solutions in the energy sector. Recycling and...
Heat transfer plays an important role in industrial and engineering applications. In this research, the effect of aluminum oxide nanoparticles on the forced heat transfer rate in laminar flow in a square cross-section channel is investigated. The governing equations are discretized by the finite difference method on the shifted grid. Nanofluid flow is simulated using single-phase and mixed...
The rise in component temperatures during operation represents one of the most significant challenges that electronic devices confront, as elevated temperatures can negatively impact their functionality and potentially lead to irreversible damage. In order to effectively tackle this problem, the utilization of synthetic jet cooling holds considerable promise for enhancing the efficiency of...
Although solar energy is one of the most promising renewable energy sources, and is considered infinite when compared to human needs, many factors such as low efficiency, large area requirements and high costs limit solar energy systems from being a suitable option to meet energy needs. In the last half century, new approaches have been developed and new research has been conducted on methods...
This study explores the synthesis, powder characteristics, and mechanical properties of an AlCrCo medium entropy alloy (MEA) fabricated via mechanical alloying (MA). Elemental powders of Al, Cr, and Co in equiatomic proportions were subjected to high-energy ball milling to achieve a homogeneous alloy. The evolution of phase formation, crystallite size, and particle morphology during milling...
Temperature control in electronic systems is of critical importance to ensure reliable and efficient operation of equipment. Heat sinks are widely used in these systems to improve heat transfer. Thermal performance of heat sinks is evaluated based on the principle of maximizing heat transfer rate with minimum pressure drop. In this study, in order to determine the effects of geometric...
Evaluating the dynamics of aerosols and particle deposition in the respiratory tract accurately is critical for studying inhalation-based drug delivery and the effects of toxic particles. This process involves complex, multiphase flows with different respiratory characteristics and plays a significant role in its impact on human health. Computational Fluid Dynamics (CFD) offers a vital tool to...
In this study, the system created by integrating aluminum foam fins of a certain thickness with pore densities of 20 PPI in a horizontal channel in a inline arrangement was experimentally investigated. Afterwards, aluminum foam fins with different thicknesses and different pore densities were integrated into the channel and numerical analyses were performed. The heat transfer and pressure drop...
The use of waste as an alternative fuel source is gaining increasing interest worldwide due to its dual benefits such as reducing energy costs and reducing environmental damage caused by improper waste disposal. It is very important to dispose of waste materials such as used tires that have reached the end of their service life and transformer oils that were once used as heat transfer fluids...
Diesel engines, one of the biggest sources of global warming and harmful exhaust emissions, constitute an important research topic in terms of reducing dependency on fossil fuels and environmental damage. The limited life of fossil-based fuels and the increase in energy demand increase the need for sustainable energy solutions that require the evaluation of waste. In this context, the...
Energy is the most important fundamental factor in the development and prosperity of societies. Today, approximately 80% of global energy consumption comes from fossil fuels. Renewable energy sources have significant effectiveness in reducing dependence on fossil fuels such as natural gas, oil and coal. Heat pumps have enabled low-grade energy sources such as geothermal, soil, sun, and air to...
The adoption of solar water heating systems not only minimizes reliance on fossil fuels but also supports global sustainability efforts by mitigating environmental impacts and promoting energy security. As solar energy remains a cornerstone of renewable energy technologies, advancements in hybrid systems and FPSWH designs are crucial to sustainably address the rising global energy demand. This...
The rapid increase in the world's population and the development of industry cause the energy need to increase very rapidly. One of the most important problems in our country, as in the world, is the increasing energy need. Renewable energy sources are being used today to meet the increasing energy need and reduce external dependency. Hydroelectric Power Plants (HES) are being built in order...
Two-phase flow with boiling and the heat transfer associated with these flows are gaining increasing importance in industrial applications due to the fact that they provide higher heat transfer coefficients compared to single-phase flows. In this study, the dynamic instabilities of two-phase flow in a horizontal empty pipe with a diameter of 13.7 mm were investigated using a forced convection...
Periodic control in safe production is critical to ensure the health and safety of employees in workplaces, to ensure the smooth operation of equipment and to maintain the sustainability of production processes. Thanks to periodic controls, potential risks are identified in advance and necessary precautions are taken. Regular control of machinery and equipment used in the workplace ensures...
Microalloyed steels are widely used in many industries due to their high strength, light weight and weldability. These steels, which are preferred for components such as chassis and body structures in automotive manufacturing, require welding joining methods to adapt to complex designs. For these steels, which are generally joined by methods such as fusion, laser and resistance welding, fusion...
