Abstract

Sound waves are very frequent in everyday life, although they are never seen. The particles of the average vibrations are parallel to the direction of propagation of the wave. In this article, the effect of changing the frequency of the sound wave on standing waves was investigated with different hertz frequencies to show technical images that can be visually translated to give fundamental predictions about the origin of the musical combinations, as it was proved that the sound is a pressure wave by giving the vibrations one side while the gas is released the other side. To obtain accurate results, the variables were fixed in the experiment as the type of gas supplied for the same experiments. It is also installed so that the distance between the diaphragm and the amplifier does not differ. The results analyzed after numerous data collection and calculations verify that the generated wavelength and frequency are directly proportional. As the frequency specified in Hz increased, the number of inverse nodes and nodes also increased. Obtaining standing waves helps to understand the nature of sound as a pressure wave, and to give all the details about the experiment and evaluate it. Sources of error and possible solutions to overcome these problems are also mentioned.

Abstract

With increasing environmental concerns about emissions, improving combustion systems for alternative fuels, such as used engine oil, has become imperative. Investigating innovative burner designs to enhance fuel-air mixing, reduce emissions, and stabilize performance presents challenges due to high viscosity and incomplete combustion. However, previous research has not adequately addressed the role of burner head geometry in mitigating these problems. A combination of experimental tests and computational fluid dynamics (CFD) simulations was used to evaluate the performance. This study aims to fill the gap by evaluating the effects of three burner head designs—axial diffuser tube, perforated distribution node, and symmetrical axial cooler—on combustion efficiency and emissions. The results indicate that the axial diffuser tube achieved the highest efficiency (94.3%) and lowest emissions (NOx: 128 ppm, CO: 52 ppm, PM: 18 μg/m3) due to uniform heat distribution and increased turbulence. The perforated distribution node showed a balanced performance, with an efficiency of 91.7% and moderate emissions (NOx: 145 ppm, CO: 65 ppm, PM: 24 μg/m³). Meanwhile, the symmetric axial cooler, designed for thermal stability, showed lower efficiency (89.6%) and higher emissions (NOx: 167 ppm, CO: 78 ppm, PM: 30 μg/m³). The results indicate the importance of burner engineering in balancing efficiency and emissions control. The results of this study support sustainable combustion technologies for industrial and domestic applications, and underscore the global transition to clean energy solutions. Keywords: Burner head design, CFD simulations, Combustion efficiency, Emissions reduction, Geometric engineering, Waste automotive oil.
