Defect Diagnosis and Modelling for A Rotating Machine Running at A Steady PaceBy Rajeev Kumar, Ravi Kant Singh, Ravi Shankar Rai, Vikas Kumar, Rakesh Dubey, Subhash Gautam
Abstract: Rotary equipment, such as gears, shafts, pumps, and bearings, are widely used across various rotary machine in industries, often operating under different loading conditions. The fluctuations in loading can lead to fatigue failures in rotating components, significantly affecting machinery performance. To investigate the behavior of such rotating equipment under diverse operational scenarios, a numerical model has been created. This approach can replace costly and often challenging experimental methods. However, it …

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