Thermal Modeling and Optimization of Irreversible Cogeneration Power Plant
Abstract: This paper aims at studying the cogeneration system coupled with outer heat reservoir of finite heat capacity and comprises of both external as well as internal irreversibility. External irreversibility is due to the finite-rate heat transfer between the working fluid and heat reservoirs while internal irreversibility is due to heat dissipation of working fluid. Both types of irreversibility are involved in the study on introducing an internal irreversible parameter which …

Experimental Investigation of FSW on Al 6061-T6 MG Dissimilar Joints
Abstract: Friction Stir Welding (FSW) is a solid-state joining technique that has shown significant potential for welding dissimilar materials, such as aluminum and magnesium alloys, which are difficult to join using conventional fusion welding methods due to large differences in their physical, thermal, and metallurgical properties. During FSW, contact between the rotating, wear-resistant tool shoulder, the pin, and the work piece produces frictional energy. Additional thermal energy develops because of intense …

Tourism - Driven Monument Conservation and Cultural Heritage Governance:The Intercessing Role of Architecture in India
Abstract: The relationship between tourism and monument conservation has become increasingly significant in contemporary heritage management. With the continued growth of tourism, heritage sites are increasingly required to accommodate new demands of accessibility, movement, interpretation, and infrastructure, leading to conflict between conservation and development of the sites through tourism. In this sense, architecture acts as an important intermediary for such processes. This paper examines the intersection of architecture, tourism, and cultural …

Kinetic and Mechanistic Study of Isomenthol Oxidation by Trichloroisocyanuric Acid in Acidic Medium
Abstract: The oxidation reaction of isomenthol with trichloroisocyanuric acid (TCICA) was systematically investigated in acidic medium to understand its kinetics, reaction mechanism, and overall reactivity. The study was carried out under pseudo-first-order conditions by maintaining a large excess of isomenthol relative to TCICA, allowing accurate determination of the reaction rate. The progress of the oxidation reaction was monitored kinetically, and the obtained data revealed that the reaction follows first-order kinetics with …

COMPUTATIONAL AND EXPERIMENTAL ANALYSIS OF A DOUBLE PIPE HEAT EXCHANGER WITH AND WITHOUT INSERTS USING NANO FLUIDS
Abstract: In applications that need warming procedures, improved heat exchange will also significantly boost heat efficiency and reduce the expense of design and operation. Double tube heat exchangers are best suited for high temperature and high compression applications due to their simplify diameters. Although they are cheap, they disseminate to the other types in a comparatively large amount. A number of approaches were developed to accomplish the required heat transfer rate …

Mechanical and Thermal Characterization of Natural Fiber-Reinforced Epoxy Composites for Structural Applications
Abstract: Natural fiber reinforced polymer (NFRP) composites have emerged as promising alternatives to conventional synthetic fiber composites owing to their environmental sustainability, low density, and competitive specific mechanical properties. However, a comprehensive and simultaneous evaluation of both mechanical and thermal performance of jute/sisal hybrid natural fiber epoxy composites under systematic fiber treatment conditions remains insufficiently addressed in the literature. The present study investigates the mechanical and thermal characterization of jute and …

Investigation of the Compatibility of Binary and Ternary Polymer Systems
Abstract: We have obtained mechanical strength of materials as a result not by synthesizing new polymers, but by using industrial polymers. We have developed a technology for obtaining new composite materials based on industrial multi-tonnage polymers of high-strength polyethylene (HSPE), polyvinyl chloride (PVC), polyurethane thermoplastic elastomer (DUTEP), butyl rubber (BR), chlorocarboxylate polyethylene (CCPE), ethylene propylene rubber (EPR). To obtain a composition from these polymers, their mixture compatibility was first determined using …

Data Science for Environmental Modelling
Abstract: Abstract: Soil moisture is a critical Earth system variable linking atmospheric, hydrological, and ecological processes. However, observations are sparse and fragmented: in situ gauges provide point data, satellite missions (SMAP, SMOS, Sentinel-1) offer broad coverage at coarse resolutionQ, and land‐surface models (GLDAS, ERA5, etc.) yield estimates with their own biase. Here we propose a conceptual framework for integrated environmental data modelling, combining rainfall, temperature, and soil moisture information with machine …
