Characterization of distributed combustion reformed methanolblends in a model gas turbine combustor

The purpose of the air distribution system in a fluidised bed combustor is to provide a reasonably uniform spread of combustion air over the entire horizontal cross-sectional area of the bed. One of the simplest, and hence cheapest, forms of air distributor is the sparge pipe design, in which an array of horizontal pipes is fitted at the base of the bed. Combustion air is then supplied to one e...

Unmanned aerial vehicles (UAV)s have unique requirements that demand engines with high power-to-weight ratios, fuel efficiency, and reliability. As such, combustion used in UAVs are specialized to meet these requirements. There several types of UAVs, including reciprocating engines, turbine Wankel engines. Recent advancements engine design, such as the use ceramic materials microscale combustio...

This study investigates the effects of boundary layer combustion on skin friction reduction in a model scramjet combustor. The 4-equation RANS (Transition SST model) is employed as turbulence and one experimental case which involves supersonic turbulent used for validating numerical simulation method. Then wall jet device can be to inject hydrogen into designed added lower combustor engine. res...

Motivated by the potential use of catalytic materials in micro-combustor application, the primary scope of this study is to investigate the lean extinction characteristics of premixed flames in the presence of catalytic reaction. In particular, the effects of mixture dilution on the lean flammability limit are examined by adopting a stagnation-point flow system with a methane/air mixture over a...

As a fundamental study relevant to micro-combustor application, the effects of mixture dilution on the lean extinction characteristics is studied for a stagnation-point flow system with a methane/air mixture over a platinum surface. For steady conditions, the level of flammability extension by surface reaction depends strongly on the mixture dilution, such that the benefit of catalyst-assisted ...

In the present paper the characterization of the flow field generated by means of a submerged gaseous jet exited by means of a coaxial synthetic jet has been investigated. The purpose of this investigation is to infer the aerodynamic interaction of the two fluid structures that play an interesting role in several industrial applications like jet actuator, flame stability in the combustor for mi...

In the present work, detailed studies of 2D TVC are investigated by using both experimental and numerical methods. For an active cavity flow case, the present results reveal that the pressure drop value across the combustor increases with the mainstream Reynolds number (Rems) due to the higher velocity gradient between the cavity and mainstream flow. Experimental results indicate that the norma...
