Within the past decade there has been a fair amount of interest in utilizing the high energy densities of hydrocarbon fuels at the small scale. The motivation for this is primarily twofold. The first application involves the generation of electricity via the heat released by combustion, in the...

A meso-scale heat recirculating combustor has been developed for the combustion of methanol and kerosene fuels with oxygen enriched superheated steam as an oxidizer. The steam oxygen mixture is a surrogate for the decomposition products of hydrogen peroxide, and as such the combustor development...

Experimental results are presented on the role of benzene addition to H2S combustion at an equivalence ratio of three with respect to H2S (Claus condition) and complete combustion of benzene. The results are reported with 0.3%, 0.5% and 1% benzene addition to H2S/O2 flame. Combustion of H2S and...

A micro-thermocouple, microphones and microphone probes were employed to provide detailed information on key ongoing processes in a premixed swirl flame. High frequency pressure and temperature measurements were carried out to identify temperature field and acoustic characteristics of a swirl...

In India, the credit needs of dryland farmers, especially small and marginal farmers, are served largely by non-institutional sources. The formal bank ing system follows a risk-averse strategy towards lending to this segment, and does not appear to attach any significance to the generation of...

This paper develops a new continuum model based upon an improved car-following model by using a series expansion of the headway in terms of the density. The new model contains an additional speed gradient term (Anisotropic term) in comparison to the Berg's model [Berg et al., Phys. Rev. E 61(2)...

We study dielectric breakdown in a semi-classical bond percolation model for non-linear composite materials introduced by us and the relaterd breakdown exponent near the percolation thresh-old in two dimensions. The breakdown exponent after doing finite size scaling analysis is found to be tB...

Steam gasification of sugarcane bagasse has been investigated. A semi batch reactor with a fixed amount of sugarcane bagasse sample placed in steady flow of high temperature steam at atmospheric pressure has been used. The gasification of bagasse was examined at reactor and steam temperatures of...

Experimental investigations on the effect of different amounts of toluene addition to H2S combustion in oxygen under Claus condition (Φ=3) are presented. Three toluene concentrations of 0.5%, 1% and 5% in H2S are presented and compared with the baseline case of 100% H2S oxygen combustion....

Lignite pyrolysis and gasification has been conducted in a semi batch reactor at reactor temperatures of 800–950°C in 50°C intervals. CO2 has been used as the gasifying agent for gasification experiments. The objective of this investigation is to understand the mechanism of syngas evolution...
