CO2 as moderator for biomass gasification [PDF]

open access: yes, 2013
Biomass can be converted into gaseous fuel by high-temperature reactions with a gasifying agent. The gasifying agent consists, in most cases, of oxygen and of a moderator, which is usually water vapour. Here we show that waste CO2 can be used instead of,

A Non-Iterative Transformation Method for Blasius Equation with Moving Wall or Surface Gasification [PDF]

open access: yes, 2015
We define a non-iterative transformation method for Blasius equation with moving wall or surface gasification. The defined method allows us to deal with classes of problems in boundary layer theory that, depending on a parameter, admit multiple or no solutions.
