“…The authors of [7,8] suggest that photovoltaic (PV) gets its name from the process of converting light (photons) to electricity (voltage), through a process called the photovoltaic effect. Solar panel technology boasts many advantages and is a cost-effective alternative to or extension of power sources for both urban and rural applications [9][10][11]. As described above, PVs are based on photo-radiation absorption and conversion in a range of wavelengths.…”

Infrared thermography is the science of measuring the infrared energy emitted by an object, translating it to apparent temperature variance, and displaying the result as an infrared image. Significantly, acquiring thermal images delivers distinctive levels of temperature differences in solar panels that correspond to their health status, which is beneficial for the early detection of defects. The proposed algorithm aims to analyze the thermal solar panel images. The acquired thermal solar panel images were segmented into solar cell sizes to provide more detailed information by region or cell area instead of the entire solar panel. This paper uses both the image histogram information and its corresponding cumulative distribution function (CDF), useful for image analysis. The acquired thermal solar panel images are enhanced using grayscale, histogram equalization, and adaptive histogram equalization to represent a domain that is easier to analyze. The experimental results reveal that the extraction results of thermal images provide better histogram and CDF features. Furthermore, the proposed scheme includes the convolutional neural network (CNN) for classifying the enhanced images, which shows that a 97% accuracy of classification was achieved. The proposed scheme could promote different thermal image applications—for example, non-physical visual recognition and fault detection analysis.

“…In heat exchangers, the efficiency is decreased due to the boundary layer at the solid-liquid interface. To improve heat exchange rate between the fluids several methods are implemented which includes (a) surface modification of the tube wall [2], [3] (b) use of nanofluid as the working fluid [4], [5], [6] and (c) use of inserts in the internal flow [7], [8], [9], [10]. Bergles and Morton first studied about various augmentation techniques for convective heat transfer and mentioned various techniques of heat transfer as surface promoters, including roughness and treatment; displaced promoters, such as flow disturbers located away from the heat transfer surface; vortex flows, including twisted-tape swirl generators; vibration of the heated surface or the fluid near the surface; electrostatic fields; and various types of fluid additives.…”

In this present study, numerical modelling and experimental verification of heat transfer enhancement using compound technique of a concentric tube heat exchanger is done. Laminar flow is considered for both the numerical and experimental study. Among the active and passive technique, passive techniques were employed with surface roughened and insertion of twisted tape. A Computational Fluid Dynamics approach was used for numerical analysis which was further verified experimentally. The geometry of the concentric tube heat exchanger was designed in SolidWorks® and the discretization was carried out in ICEM CFD 14.5. The computational simulation was carried out by ANSYS CFX 14.5 solver. The experimental verification was conducted in the same Reynold's Number range used in the numerical analysis, of 500-5000. The heat transfer enhancement was calculated through Performance Evaluation Criteria (PEC) which was found to be 9.67 and 7.89 for CFD analysis and Experiment respectively.
