Renewable fuels may have hidden costs, study says
renewable fuels hidden costs greenhouse gas emission
2009/10/27
A global push toward production of biofuels, advocated by many as a measure to curb greenhouse gas emissions, could have exactly the opposite effect unless adequate controls are put in place, a new st...
The utility of sewage sludge as a biomass fuel is taken as an approach to deal with global warming. Thermal characterization of this new type of fuel is a premise before it is practically used in real...
INVESTIGATION INTO THE EFFECT OF DIFFERENT FUELS ON IGNITION DELAY OF M-TYPE DIESEL COMBUSTION PROCESS
ignition delay case study M-type
2009/10/14
An ignition delay is a very complex process which depends on a great number of parameters. In practice, definition of the ignition delay is based on the use of correlation expressions. However, the co...
The research presented consists of a study of the burning characteristics of a liquid fuel floating on water with emphasis in the phenomena known as boilover. The problem is of technical interest in t...
