Effect of cow dung variety on biogas production

  Biogas is a renewable, alternative and sustainable form of energy from the action of bacteria when waste vegetable matter, organic waste and some industrial waste are fermented in the absence of oxygen. This study was conducted to find the effect of cow dung variety on biogas generation. Some samples of fresh cow dung (2 Kg for each breed of cow) of cows which were not exposed to treatment with anti-biotics...

Influence of injection timings on performance and emissions of a biodiesel engine operated on blends of Honge methyl ester and prediction using artificial neural network

  In the present work, biodiesel prepared from Honge oil (Pongamia) was used as a fuel in C. I engine. Performance studies were conducted on a single cylinder four-stroke water-cooled compression ignition engine connected to an eddy current dynamometer. Experiments were conducted for different percentage of blends of Honge methyl ester with diesel at various compression ratios and at different injection...

Experimental investigation on roll forming of aluminum alloy AA6101 tubes

  Aluminum alloys are widely used in engineering structures and components, where light-weight and corrosion resistance are required. The roll forming process is successfully used for materials that are difficult to form by other conventional methods because of spring back, as this process achieves plastic deformation without spring back. In addition, the roll forming improves the mechanical properties...
