Heavy Ion Radiation Damage Track Studies in SSNTDs (Polymers, Glasses and Minerals) and Single Activation Energy Model
Abstract: My training in Marie and Pierre Curie University, Paris for the identification of relativistic particle tracks in nuclear emulsions came handy for shifting to Heavy ion track studies in solid state nuclear track detectors (SSNTDs). Track formation mechanism in both may be different, but the basic nature of phenomenon by which the tracks are produced remains essentially the same. All charged particles produce ionisation of the medium and lose energy …

Integrated Perspectives on Fluid Mechanics and Energy Transport in Complex Flow Systems
Abstract: Fluid mechanics plays a central role in understanding the transport of mass, momentum, and energy in complex flow systems encountered in both natural and engineered environments. This review presents an integrated perspective on fluid behavior by combining fundamental principles with modern approaches to energy transport analysis. The study emphasizes the significance of conservation laws and their application to diverse flow regimes, including laminar, turbulent, compressible, and multiphase flows. Energy transport …

CFD Analysis of Heat Transfer Enhancement in a Circular Pipe Flow by Swirl Flow
Abstract: Heat transfer enhancement techniques are very important to save more energy by using optimal energy sources. Heat transfer rate depends upon different parameters like Reynolds number, properties of fluid, nature of surface, mass flow rate, velocity, temperature and pressure. Many techniques are used for heat transfer enhancement in which swirl flow devices are effective. For enhancement of heat transfer, smooth pipe with tangentially injected swirl flow is better option than …

Contract and Feature Extraction of CBIR Method Using Soft Computing Techniques in Machine Learning
Abstract: There is expansion in size of picture securing and information capacity strategies and furthermore there is expansion in data set of pictures. Prior text-based depiction and manual comment of pictures were utilized for recovery of pictures that was a tedious errand. The need of great importance is to deal with the huge assortments through proficient frameworks called content-based picture recovery frameworks. For this situation visual items in the picture like …

Flow Simulation and Experimental Comparative Study of Aerodynamic Forces on NACA 2415 Airfoil Scaled Model
Abstract: Aerodynamic force, which would be brought upon by the relative motion of an object and the airflow, is the force that the air in which the body is submerged exerts on the body. The normal force resulting from force on the body's surface and the shear force resulting from airflow viscosity, also known as skin friction, are the two sources of aerodynamic force. Shear force is applied locally and parallel …

Review on UV – Visible Spectroscopy and HPLC
Abstract: Like Fourier-transform infrared spectroscopy, UV-visible spectroscopy is used to determine the purity of pharmaceutical compounds. Many substances have chromospheres, which absorb certain wavelengths of ultraviolet or visible light. Using the Beer–Lambert equation, the absorption of spectra obtained from these samples at given wavelengths can be directly related to the sample concentration. Normally, UV and UV-visible spectra are recorded at high and low pH, and the results of both are compared …

Thermo-hydraulic Performance of Multi-Pass Double-Pipe Heat Exchangers: Integrating Polymer Composite Tube Wall Materials via CFD Parametric Study and Experimental Validation
Abstract: Metallic materials such as steel and copper have traditionally dominated heat exchanger manufacturing because of their excellent thermal conductivity, mechanical strength, and long-established industrial reliability. However, their high weight, susceptibility to corrosion in aggressive operating environments, and inability to provide tunable thermal properties have motivated interest in alternative materials for next-generation thermal systems. Thermally conductive polymer composites reinforced with graphene nanoplatelets (GNP), boron nitride (BN), and carbon-based fillers offer an …

Thermo–Electrical Performance Enhancement of a Lightweight Polymer–Metal Hybrid Electrostatic Precipitator Using Epoxy-Based Composite Housing for Industrial Particulate Control
Abstract: Airborne particulate emissions, particularly PM₁₀ and PM₂.₅ produced by industrial activities and combustion processes, they continue to pose a significant threat to both the environment and public health. Electrostatic precipitators (ESPs) are widely recognized for their ability to achieve high collection efficiencies; however, conventional metallic constructions often lead to increased system weight, higher fabrication costs, and long-term corrosion-related challenges. In this study, a lightweight hybrid material approach is proposed by …

Q Anisotropy in the Region of Garhwal Himalaya
Abstract: Abstract Empirical relations have been found out to describe the decay in amplitude with distance of s-waves in the region of Garhwal Himalaya. These functions results from the analysis of spectral amplitudes of three component digital records from 19 local earthquakes obtained from 12-station seismological network deployed in the Garhwal lesser Himalaya. The events lie in a magnitude range from ML 2 to ML 4.5, epicentral distance 5 to 120 …
