This study develops a 3D-CFD model to analyze the thermal performance of perforated fin heat sinks and evaluates four perforated continuous and interrupted fin heat sinks with distinct geometric patterns. Using the Finite-Volume Method (FVM) to discretize the governing equations, the SolidWorks 2019 flow simulation software was implemented to solve and validate the latter, demonstrating that the CFD simulation model employed in the current study is reliable. The performance parameters of the heat sink are presented in terms of Reynolds number and heater power. The results indicate that modules B and C achieved higher heat transfer rates, average heat transfer coefficient, and Nusselt number compared to the other modules. Module A had the highest fin efficiency and module D exhibited greater fin effectiveness than the other ones.
... The success of plastics emerges from the numerous technical and economic advantages they have compared to other non-plastic materials: absence of corrosion, low price, low mass, flexibility, etc. [2][3][4][5][6][7]. Plastics are used in various applications by numerous industries, such as electronics and household appliances, textiles, packaging, cars, ships and aircraft, medical and optical materials [8][9][10][11][12][13][14][15]. Polyethylene (PE) is utilized mainly in the distribution networks of natural gas, drinking water, and wastewater [1,[16][17][18][19][20][21]. ...
This paper presents the tensile strength and Shore D hardness behavior of electrofusion-welded and artificially aged polyethylene (PE) pipes of the PE100 SDR11 classification with a nominal diameter of 125 mm and a wall thickness of 11.40 mm. For the study, 12 samples were taken from the body of a PE100 SDR11 pipe (9 of which were obtained from the fusion-welded joint). Subsequently, the 12 samples were divided into 3 groups of 4 pieces (1 unwelded sample and 3 welded samples). Following the Arrhenius method, the samples of the 2 groups (group II and group III) were artificially aged, those belonging to group II were aged 10 for years and those belonging to group III were aged for 20 years. Subsequently, all 12 samples were tested for tensile strength and Shore D hardness. The 10-year aging of the welded samples increased the tensile strength by 12.31% and the 20-year artificial aging increased the tensile strength by 18.44%. For the unwelded samples, artificial aging for 10 years increased the tensile strength by 11.12%, whereas aging for 20 years increased the tensile strength by 12.63%. Artificial aging of the PE100 SDR 11 pipes does not have a significant influence on the Shore D hardness, which was found within the high range of hardnesses. The results show that the PE100 SDR pipes welded by electrofusion can be used for 20 years with safety.
... The mud pump is an essential equipment for ensuring the required flow rate of the circulation system during drilling. It extracts the drilling fluid from the mud tank and injects it into the well bottom through the drill rod, removing the debris produced during the drilling process to the surface [1]. Due to a large amount of sediment usually present in the mud and the high-pressure condition of the mud pump, the intake valve, discharge valve, and piston of the mud pump are prone to failure, causing leakage of fluid and reducing the pressure generated by the mud pump, thereby affecting the normal progress of drilling work. ...
Mud pumps serve as vital components within the circulating system of oil drilling platforms, primarily facilitating the circulation of drilling fluid. With the rapid advancement of deep learning technology, there has been a growing focus on fault diagnosis techniques for mud pumps based on deep learning methodologies. However, existing deep learning approaches often struggle with fault diagnosis of mud pumps under varying operational conditions, as adjustments to the working conditions are necessary in real-time based on drilling depth. To address this challenge, this study introduces an enhanced transfer learning method for diagnosing faults in mud pumps across different operating conditions. Initially, the collected vibration data undergoes resampling to standardize frequency, followed by the utilization of the short-term autocorrelation method to discern phase information of signal impact. Leveraging this phase information, the signal is segmented into distinct segments with uniform phases, thereby minimizing distribution discrepancies between the source and target domains. Subsequently, the transformer is employed as a feature extractor for the model. Finally, a deep sub-domain adaptation network is employed to facilitate transfer from the source domain to the target domain. Validation of the proposed method was conducted using an experimental dataset, with results demonstrating its efficacy compared to other contemporary approaches.
... INTRODUCTION Polyethylene (PE) has become one of the most widely used thermoplastic materials due to its many technical and economic advantages compared to other materials in this range [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The major advantage of this plastic material is that it can be repeatedly softened and reshaped under heating without changing its core structure and properties, [12,26,20]. ...
This paper presents the results of an experimental study on the influence of aging on the shore A hardness and tensile strength of butt-welded PE100 SDR11 pipeline joints with a nominal diameter of 125 mm and wall thickness of 11.40 mm used in natural gas distribution transportation. For the experimental determination, 12 samples were taken from the body of the pipe, 9 of which were taken from the area of the butt-welded joint. The test tubes were divided into 3 groups of 4 pieces each (1 unwelded test tube and 3 welded test tubes). Using the Arrhenius method, the test tubes in 2 groups were given artificial aging treatments of 10 and 20 years. Subsequently, all 12 test tubes were tested for shore A hardness and tensile strength. For the welded samples, an increase in tensile strength was observed with increasing aging time by 6.5% for the 10-year aged samples and by 6.16% for the 20-year aged samples. For the unwelded samples, the tensile strength decreased by 3.57% for 10-year aging and increased by 5.84% for 20-year aging. Artificial aging of 10 and 20 years of natural gas transmission and distribution pipelines did not considerably influence the Shore A hardness values, as they were in the medium/soft hardness range.
... The infill percentage refers to the amount of material used to fill the interior of the part. A higher infill percentage generally results in a stronger part, but may also increase weight and printing time [14][15][16][17]. The printing process can be optimized to produce parts with the desired balance of strength, weight, and surface finish by varying both these parameters [18]. ...
Charpy impact testing is a widely used method for the evaluation of the toughness of materials, including 3D-printed plastic parts. This study performed Charpy test on 3D-printed samples made of PLA and ABS. Factors such as layer thickness and infill percentage varied (0.10, 0.15, and 0.20mm layer height and 50, 75, and 100% infill percentage) to investigate how they affect the mechanical properties of 3D printed parts, including their toughness.
