<p>The ability of wind energy to produce energy steadily and consistently makes it an important and necessary energy source. However wind energy has faced many challenges, such as discontinuation of wind farm equipment, early investment costs and therefore finding wind energy efficiency areas. The main aim of this project is to determine the energy efficiency of wind turbines, and it will also help to make suggestions to reduce the maintenance costs of wind turbines. In this study, data analysis of turbine generators was performed daily using machine learning and deep learning algorithms to obtain wind speed data for the day. We present an approach that leverages deep learning and machine learning algorithms to reliably estimate variable costs. Therefore the performance of machine learning and deep learning algorithms is reviewed. For long term forecasts, these algorithms can be used in conjunction with electricity generation costs that historical correlations with wind speed data.</p>J MahalakshmiK.M. Annammal

https://engineeringjournals.stmjournals.in/index.php/TMD/article/view/7758
<p class="abstractcAB">Resistance Spot Welding of thin (RSW) low carbon steel sheets are widely used in automotive, aero-space sectors, furniture, medical equipments, packaging and electronics industries. Although, RSW is well established for low thickness sheets and static design guidelines are well defined, the dynamic analysis of spot welded panels has not been studied in detail. In this paper, solid modeling is done using Solid Works incorporating all the spot weld geometrical features like thicknesses of the two sheets that are joined, over-lap distance, spot size, nugget height, pitch distance, orientation of spot weld axis with respect to fixed end axis and type of clamping. Step by step procedure has been described with emphasis on the choice of appropriate commands so that meshing is smooth and continuous. Dynamic analysis of RSW panel is then analyzed with respect to modal frequencies and mode shapes for the first four modes for different boundary conditions such as all ends free (FFFF), one end clamped, CFFF (Clamped-Free-Free-Free), two ends clamped CFCF, (Clamped-Free-Clamped-Free) and all ends clamped (C-C-C-C). Experimental Modal Analysis has also been carried out on spot welded panels using FFT analyzer. The results obtained from Solid works are in close agreement with experimental findings, thus validating the model.</p>Jagadeesh BagaliN.V. NanjundaradhyaRamesh S. SharmaV.L. Jagannatha Guptha

2024-03-272024-03-2732293910.37591/tmd.v10i3.7758A Review on Increases the Heat Transfer Rate of the Solar Air Heater by Adding the Fins in the Absorber Plate
https://engineeringjournals.stmjournals.in/index.php/TMD/article/view/7757
<p>Solar air heaters are extensively utilised in a diverse range of domestic and industrial settings. The need to enhance the thermal efficiency of solar air heaters has prompted researchers to concentrate on enhancing the thermal performance through the implementation of artificial flow modification techniques in the flow field. Consequently, the presence of this phenomenon will disrupt the laminar sublayer located beneath the absorber plate, so contributing to an elevation in the amount of turbulence within the air. Consequently, there is an augmentation in the rate of heat transmission from the absorber plate. This paper examines the impact of diverse turbulator shapes employed by researchers on enhancing the thermal efficiency of air heaters. The paper extensively examines various design factors, geometries employed, flow conditions, and their impact on turbulence, heat transfer rate, absorber temperature, and thermo-hydraulic enhancement factor. In conclusion, this study presents the last remarks and suggests future directions for further improving the performance of solar air heaters.</p>Usmani Yasir ArquamShivendra Singh

2024-03-272024-03-273281610.37591/tmd.v10i3.7757A Review on Behavior of Heat Transfer in the Fluid in Shell and Tube Type Heat Exchanger
https://engineeringjournals.stmjournals.in/index.php/TMD/article/view/7756
<p>The primary objective of this literature analysis is to examine the many applications of "Computational Fluid Dynamics (CFD)" within the domain of heat exchangers. "Computational Fluid Dynamics (CFD)" has been utilized in several investigations relating to heat exchangers, including fluid flow maldistribution, fouling, pressure drop, and thermal analysis during the stages of design and optimization. The simulations conducted demonstrate that the solutions generated from CFD are generally within the permissible range, hence substantiating the efficacy of utilizing CFD as a predictive technique to analyze the behavior and performance of various heat exchangers. This research aims to investigate the potential improvement in heat transfer rate within a heat exchanger by modifications made to its design.</p>Md. Ahsan AlamLakshmi YadavAshish Muchrikar

https://engineeringjournals.stmjournals.in/index.php/TMD/article/view/7712
<p>This paper presents an application of concentric flow mode of dry dielectric (compressed air) supply for ultrasonic assisted wire electric discharge machining process (CFDUAWEDM). The concentric flow mode of dielectric supply using ultrasonic assistance is expected to offers improved surface integrity, environmental and operator friendliness during wire electric discharge machining (WEDM) process. Experimental set up was developed wherein, the ultrasonic vibration was applied to the electrode wire using an ultrasonic stepped horn and compressed air was injected concentrically into the machining gap through a nozzle around wire. Experiments were performed varying control parameters and responses were recorded. Experimental results indicated that the cutting velocity was affected by current, kerf width of the cutting slot was significantly affected by the pressure and pulse off time. Moreover, air pressure influenced the surface roughness significantly. It was observed that there exists an optimal relationship between response parameters and amplitude. The empirical models of the cutting velocity, surface roughness and kerf width have been developed using the regression analysis to investigate the statistical behavior of process. Results obtained suggested that the concentric flow with ultrasonic assistance can be an alternate to conventionally used dry WEDM. Concentric flow with ultrasonic assistance of dielectric supply method has the potential to overcome inherent drawbacks of dry WEDM.</p>Bharat C KhatriPravin P. RathodC.D. Sankhavara

https://engineeringjournals.stmjournals.in/index.php/TMD/article/view/7711
An abstract describing a PVC pipe cutting tool based on Nichrome 80 wire is provided. The cutting tool consists of a frame, a handle, and a high-resistance nichrome 80 cutting wire that generates heat when an electrical current passes through it. The wire is mounted between two fixed posts on the frame and is powered by a battery-operated electrical source. All the user has to do is hold the handle and move the wire along the PVC pipe. The wire heats up rapidly and cuts through the pipe with ease, precision, and cleanliness. The cutting tool is ideal for use in a variety of situations because it is lightweight and portable. The main advantages of conventional cutting tools such as Hacksaws and Miter saws are that they are simple to use and they require minimal training, making them accessible to a wide range of users. They are also very cheap. However, they have a number of drawbacks, such as poor cutting accuracy, increased labor needs, and shorter tool life. Our new design aims to address these shortcomings of the traditional tools. The cost of the new design is only slightly higher than that of the conventional tools. A patent application will be submitted at a later time to protect its intellectual property because of its unique design and functionalityAmal RAjith K.G.NAlex Mathew GeorgeBalakrishna K.PFebin Santhosh
