Flow of a Thermoviscous Fluid through an Annular Tube with Constriction

The flow of thermoviscous fluid within the annulus of circular cylinders with a localconstriction at the outer wall is investigated analytically, assuming that the constriction is non-symmetric wrt the radial distance.  Analytical solutions for velocity and temperature fields havebeen obtained. The effect of the shape parameter of the constriction on velocity, temperature,Nusselt number, and flow rate are illustrated graphically and discussed

Usage of Electronic Resources by the Faculty Members of Sri Ramakrishna Engineering College, Coimbatore: A Study

This paper examined the awareness and usage of e-resources by the faculty members of Sri Ramakrishna Engineering College. The present study is based on primary data collected from the faculty members working in the various departments of Sri Ramakrishna Engineering College. This study is conducted using a total number sample of 277 Faculty Members were randomly selected from thirteen departments. The data were collected by using empirical method of the questionnaire. The study aims to analyze the awareness and purpose of e-resources, frequency of using e-resources, Utilization and Satisfaction level of e-resources. It is found that the majority of faculty members are highly aware on IEEE 218 (86.17%), Springer Open 128 (50.59%) and O’reilly Open book and Free Engineering books 91 (35.97%) and further found that majority of 203 (80.24%) faculty members fully satisfied with about NPTEL resources

CONSEQUENCES OF WEIGHTED VEST AND WEIGHTED SLED RUNNING ON ELASTIC POWER OF SCHOOL SPRINTERS

The purpose of the study was to cause of weighted vest and weighted sled running on elastic power of school sprinters. To achieve the purpose of this study, forty five male sprinters from the Public school. The age, height and weight of the subjects ranged from 17 to 19 years, 155 to 165 centimetres and 50 to 55 kilograms in that order. They were divided into three groups; each group consisted of fifteen subjects. Group-I underwent weighted vest sprint training, group-II underwent weight sled training and group-III acted as control who does not participate in any training programme. The data collected from the three groups prior to and post experimentation were statistically analyzed by analysis of covariance (ANCOVA). When the obtained ‘F’ ratio value in the analysis of covariance test was significant, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. In all the cases, statistical significance was fixed at .05 levels. Conclusion: The experimental group sprinters had significant improvement on elastic power when comparing to the control group sprinters.  Article visualizations

Combined effects of chemical reaction and temperature dependent heat source on MHD mixed convective flow of a couple-stress fluid in a vertical wavy porous space with travelling thermal waves

A mathematical model is developed to examine the effect of chemical reaction on MHD mixed convective heat and mass transfer flow of a couple-stress fluid in vertical porous space in the presence of temperature dependent heat source with travelling thermal waves. The dimensionless governing equations are assumed to be made up of two parts: a mean part corresponding to the fully developed mean flow, and a small perturbed part, using amplitude as a small parameter. The analytical solution of perturbed part have been carried out by using the long-wave approximation. The expressions for the zeroth-order and the first order solutions are obtained and the results of the heat and mass transfer characteristics are presented graphically for various values of parameters entering into the problem. It is noted that velocity of the fluid increases with the increase of the couple stress parameter and increasing the chemical reaction parameter leads suppress the velocity of the fluid. Cross velocity decreases with an increase of the phase angle. The increase of the chemical reaction parameter and Schmidt number lead to decrease the fluid concentration. The hydrodynamic case for a non-porous space in the absence of the temperature dependent heat source for Newtonian fluid can be captured as a limiting case of our analysis by taking, and α1→0, Da→∞, a→∞

Directional Freeze-Casting : A Bioinspired Method to Assemble Multifunctional Aligned Porous Structures for Advanced Applications

Herein, the potential of directional freeze-casting techniques as a very generic, green, and straightforward approach for the processing of various functional porous materials is introduced. These materials include 3D monoliths, films, fibers, and microspheres/beads, which are obtained by the assembly of network building blocks originated from cryoassembly of the various aqueous-based systems. The process simply relies on 1) directional freezing of the slurry through contact with a cold surface, 2) maintaining the slurry at the frozen state for a particular time with controlling the freezing parameters and directions, and 3) sublimation of the created ice crystal templates inside the developed structure to translate the ice growth pattern to final porous structure. The materials developed with such a cryogenic process contain a highly complex porous structure, e.g., a hierarchical and well-aligned microstructure in different levels, which renders a high control over the physicochemical and mechanical functionalities. Due to the versatility and controllability of this technique, the process can also be extended for the mimicking of the structures found in natural materials to the bulk materials to assemble bioinspired porous composites with many useful mechanical and physical features. The aim, herein, is to give a brief overview of the recent advances in developing anisotropic porous inorganic, organic, hybrid, and carbonaceous materials with a particular emphasis on materials with biomimicking microstructure using directional ice templating approach and to highlight their recent breakthrough for different high-performance applications.Peer reviewe
