“Precision oriented, motivated and energetic. I got to work with Ranjith for 3 years as an internal customer in product development at Bosch India. In addition to deliver the simulation results with best documentation, he always suggested us improvements in design. He was also very open minded to even learn the local language and communicated to people in their own language which made his network much stronger.”

Numerical Modeling of Energy Transport Between Cooling Air and Fibers in Dry Spinning Process
American Institute of Chemical Engineers (AIChE)
Dry spinning is a popular method of spinning dissolved polymers such as polypropylene, acrylics and modacrylics. In this process, the polymer is dissolved in the organic solvent at high temperature and is extruded through a spinneret having hundreds of holes. A stream of conditioned air is passed through the nozzle placed across the extruded fibers in the air gap to initiate the cooling of polymer/fiber.

Dry spinning is a popular method of spinning dissolved polymers such as polypropylene, acrylics and modacrylics. In this process, the polymer is dissolved in the organic solvent at high temperature and is extruded through a spinneret having hundreds of holes. A stream of conditioned air is passed through the nozzle placed across the extruded fibers in the air gap to initiate the cooling of polymer/fiber. Polymer stretching in this air gap helps in achieving the desired fiber tenacity. Hence the air gap and the cooling air properties play crucial roles in stable spinning.
The present work focusses on understanding the energy transport phenomena between the cooling air and the fibers in the air gap. Dry spinning module in commercial CFD solver, ANSYS Fluent, is used to account for the two way coupling between the fibers and the cooling air. Due to the limitation in this module, the fiber is assumed to behave as a Newtonian fluid. The convective energy transport between the fibers and the surrounding air has been modeled using the Kase-Matsuo correlation for the cross flow conditions. The model does not account for the fiber dynamics and the mass transfer between the fiber and the air. The model predictions are validated with the experimental trials in terms of the velocity and the temperature of the air in the air gap. The model provides insights on the profiles of fiber temperature, strain rates, diameter, velocity etc. at various points along the fiber length in the air gap. These profiles are rather difficult to measure during experiments in these prevailing conditions. To gain further understanding into the air-fiber interactions, the effects of temperature & mass flow rate of the cooling air, spinneret hole density and initial fiber diameter are investigated. This developed understanding can help in achieving the stable spinning.Other authorsSee publication -
Fault diagnosis of antifriction bearings through sound signals using support vector machine
Journal of Vibroengineering

stage. Sound signals of the bearings can be used to continuously monitor bearing life. This
paper uses sound signals acquired in bearings under healthy and simulated faulty conditions for
the purpose of fault diagnosis through machine learning approach. The statistical features were
extracted from the sound signals. Significantly important features were selected using J48
decision tree algorithm. Support Vector Machine (SVM) is used as a classifier. The selected
features were given as inputs for the c-SVM and ν-SVM (nu – SVM) model of SVM and their
classification accuracies were compared. -

Bearing is one of vital transmission elements, finding numerous applications in small, medium and large machineries. Vibration signals of a rotating machine contain the dynamic information about its operating condition. This paper uses the vibration signals acquired in bearings under healthy and simulated faulty conditions for the purpose of fault diagnosis through machine learning approach. The descriptive statistical features were extracted from vibration signals and the important attributes were selected using decision tree (dimensionality reduction).The selected features were then used for classification using J48 decision tree algorithm. The paper also discusses the effect of various parameters on classification accuracy.

Finite element method to simulate the deformation of metals at the atomic level
-
A Finite Element Method has to be developed to study the behavior of the materials at the atomic level considering the factors like voids, slips and dislocations. This study will make use of the standard available commercial Finite Element packages without creating the new codes/Elements for simplicity. Iron (Fe Bcc) structure will be considered as the benchmark material to study, and subsequently this method will be tested to all crystal structures.

Vibration Control using Constrained Layer System

Vibration is one of the most important factors to be considered while designing a mechanical system. In case of a car, the passenger to enjoy a better ride comfort, the system should be free from vibrations. Although all materials exhibit a certain amount of damping, many (steel, aluminium, magnesium and glass) have so little internal damping that their resonant behaviour makes them effective sound radiators.

Vibration is one of the most important factors to be considered while designing a mechanical system. In case of a car, the passenger to enjoy a better ride comfort, the system should be free from vibrations. Although all materials exhibit a certain amount of damping, many (steel, aluminium, magnesium and glass) have so little internal damping that their resonant behaviour makes them effective sound radiators. By bringing structures of these materials into intimate contact with a highly damped, dynamically stiff material, it is possible to control these resonances. The common methods of controlling unwanted intensity of mounted machinery vibrsations are: (i) proper design to reduce the excitation at source, (ii) changing of mass and/or stiffness to avoid resonance, and (iii) using damping materials. In this review we will be discussing about the various types of vibration control methods and the advances which had taken place in the area of vibrations.
The bottom line in noise and vibration control, as in virtually all other engineering efforts, is cost-effectiveness, which translates into achieving workable, inexpensive solutions to complex problems. Maximum advantages of reducing noise and vibration at the source can be realized by careful planning, thoughtful design, and proper choice of materials and structures specifically engineered for the task.
This technological state of the art in damping materials and systems is such that it is possible to design products that operate more quietly, with less vibration and greater precision, without being necessarily more expensive or difficult to build. -
