    Integration of Modular Multilevel Converter Topology in the Design and Control of Hybrid Electric Vehicles

    By Subhash Gautam, Devendra Singh Kushwaha, Rahul Singh Rajawat, Kaveri Jadhav, Ravi Kant Singh, Rajeev Kumar

    Abstract: A back-to-back modular multilevel converter (BMMC) based plug-in hybrid electric vehicle power conversion system is proposed to solve the problems of traditional MMC-EV. The local AC harmonics generated by the operation of MMC-EV accelerate the battery degradation and reduce the battery life. Currently, electric vehicles are in great demand due to the rising oil prices and environmental pollution concerns. Since the backbone of electric vehicles is the energy storage system, …

    Enhancing Delamination Resistance in CFRP Composites through surface Functionalization of Woven carbon Fiber by CuO Nanostructures

    By Ravi Shankar Rai, Vikas Kumar, Rajeev Kumar

    Abstract: In order to produce a nanostructured interphase that improves the interfacial interaction with an epoxy resin matrix, copper oxide (CuO) nanostructures were hydrothermally formed onto woven carbon fibers (WCF). Hexagonal CuO nanorods were created using a two-step, seed-assisted solvothermal technique on plain woven carbon fiber. This study investigates the effects of surface modification of carbon fibers by the formation of CuO nanostructures using a hydrothermal technique on the mechanical properties …

    Thermal Management of Different Composites Materials Using a Convergent and Straight Vortex Tube

    By Ravi Kant Singh, Pankaj Dashore, Rachana Dashore, Vandana Purushottam Chitodkar, Shraddha Bhausaheb Navle, Supriyatai Kailashrao Ahire, Rajeev Kumar, Subhash Gautam

    Abstract: The present study focuses on an in-depth and meticulous exploration into the intricate realm of thermal management in three distinct yet widely utilized composite materials—namely, Liquid Crystal Polymer (LCP) Composites, Glass Fiber Reinforced Polymers (GFRPs), and Aramid Fiber Composites (Kevlar). This investigation employs an innovative counter-flow vortex tube system, meticulously analyzing and comparing the thermal efficiency of these materials under different intake configurations. Specifically, two distinct geometrical intake designs—a straight …

    Process Parameters Optimization of Fiber Laser Cladded SS316 Surface Using RSM Analysis

    By Vikas Kumar, Ravi Shankar Rai, Rajeev Kumar

    Abstract: This paper presents the laser cladding experiments on the surface of SS316 to study the variations in process parameters, such as scanning speed (100-250 mm/min), laser power (50-250 W), and % volume of B4C (5- 25%) + SS316 powder on the mechanical, metallurgical and tribological performance of the modified surface. A central composite design (CCD) was used to develop the response surface methodology (RSM) to design the experiments and for …
