This paper presents results obtained from corncob combustion in a pilot scale vortexing fluidized bed combustor (VFBC). Three combustion modes including direct combustion, staged combustion and flue gas recirculation (FGR) combustion were employed, and their combustion and pollutant emission characteristics were studied. In addition, the effects of combustion fraction and bed temperature on pol...

In order to service and grow in the present day of global competition, every manufacturing concern focuses mostly on two factors i.e. productivity and quality. Laser drilling is a popular non-traditional machining technique for producing large numbers of cooling holes of various sizes (less than mm diameter) and angles in modern aerotech components such as turbine blades, injector nozzles, and ...

Energy efficiency is likely to influence the characteristics and magnitude of residential energy demand in the future. In particular, improved thermal insulation, patterns of appliance ownership, and turnover of housing stock will change the residential energy landscape. The economics of residential micro combined heat and power (micro-CHP) a technology to provide heat and some electricity to i...

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...

The existing methods for detection of the cloud scenes are applied at relatively small spectral range within shortwave upwelling radiative wavelength flux. We have reported a new method based on Radiance Enhancement (RE). This can be used to cover significantly wider from 1100 nm 1700 by using datasets space-orbiting micro-spectrometer Argus 1000. Due high sunlight reflection smoke originated f...

This paper presents a review on the combustion mode design with high efficiency and low emissions controlled by fuel reactivity and mixture stratification that have been conducted in the authors’ group, including the charge reactivity controlled homogeneous charge compression ignition (HCCI) combustion, stratification controlled premixed charge compression ignition combustion, and dual-fuel com...
