Design and Analysis of S-Glass Heat Exchanger
Abstract: This paper focuses on the composite material named S-Glass fibre Heat Exchanger. Since the existing design of heat exchangers are generally made up of metals which produce a critical amount of heat loss to the surrounding from the shell. These are also less corrosive resistant, have low life and high weight. To overcome these drawbacks, use of composite materials has become essential. There is a need to redesign using composite …

Numerical Analysis of Cyclone Separator
Abstract: The fluid dynamics of a three-dimensional cyclone separator were studied computationally. Commercial CFD software package, Fluent was used for the simulation. A multiphase Eulerian-Eulerian model incorporating the kinetic theory of granular flow (KTGF) was applied for simulating the air-solid movement. Momentum exchange coefficients were calculated using the Gidaspow drag functions. The kinetic energy fluctuation of mixture was characterized by varying the pressure values from 98Pa to 180Pa. Further computational and …

Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …

Reduction of Pollutant for SI Engine Using Argon and Oxy-hydrogen
Abstract: Reducing the emission associated with oil combustion is gaining increasing interest worldwide. Due to their dangerous effects on human health, vegetation and climate, various pre-combustion, in-cylinder and post combustion techniques have been tried for their abatement. The combustion of a hydrocarbon fuel with air produces mainly carbon dioxide(CO2) and Water(H2O). However, internal combustion engines are not perfectly efficient, so some of the fuel is not burned, which results in the …
