The photoacoustic effect - production of sound from light - may be exploited for detection and localization of gas leaks on the surface of otherwise sealed components. The technique involves filling the test component with a photoactive tracer gas, and irradiating the component to produce photoacoustic sound from any leak site where a tracer gas cloud forms. This presentation describes experiments utilizing 10.6-micron radiation from a carbon-dioxide laser with sulfur hexafluoride as a tracer gas. Here, photoacoustic sounds from a laminar plume ....etc

SF6 Gas insulated Substations (GIS) are preferred for voltage ratings of 72.5KV, 145KV, 245KV, 420KV and above. In such a situation, the various equipments like circuit breakers, busbars, isolators, and load break switches; current transformers, voltage transformers, earthing switches etc. are housed in metal enclosed modules filled with SF6 gas.

The SF6 gas provides the phase to ground insulation. As the dielectric strength of SF6 gas is higher than the air, the clearances required are smaller. Hence, the overall size of each equipment and ....etc

A dense gas is defined as any gas whose density is greater than the density of the ambient air through which it is being dispersed. This result can be due to a gas with a molecular weight greater than that of air or a gas with a low temperature due to auto-refrigeration during release, or other processes. The importance of dense gas dispersion has been recognized for some time. Early field experiments (Van Ulden, 1974; Puttock et al., 1982; Koopman et al., 1984) have confirmed that the mechanisms of dense gas dispersion differ markedly from neu ....etc

INTRODUCTION

A. Relevance :-
The economic of India depends to a large extent on the wheels of transport. The specter of economy ruin due to depleted oil reserves has changed the interest of scientist and research work towards alternative fuels for motor vehicle. Viable substitute for motor spirit are gaseous hydrocarbons, hydrogen gas, alcohol & electricity that run on hydrocarbon gas & electricity are still in the experimental stage. While alcohol is used as a fuel chiefly in Brazil, it?s feas ....etc
