ASSESSING IP, FP AND BP OF DIESEL ENGINE FUELED WITH DIESEL AND WATER-IN-DIESEL EMULSION USING DIFFERENT SURFACTANTS
The intention of this study was to investigate the effect of surfactant over a water-diesel mixture to make an emulsified fuel. The total surfactant concentration in each of the diesel-water emulsion samples studied (span 20, span 80, tween 20, tween 80) was fixed at 1% w/w. The water content was variable at 5-15% w/w. The non-ionic surfactants used in this study tend to reduce the interfacial ten...

LOCAL STRAIN RATE AND CURVATURE DEPENDENCES OF SCALAR DISSIPATION RATE TRANSPORT IN TURBULENT PREMIXED FLAMES: A DIRECT NUMERICAL SIMULATION ANALYSIS
Thestatistical behaviours of the instantaneous scalar dissipation rateNc of reaction progress variable c in turbulent premixed flames have been analysed based on three-dimensional direct numerical simulation data of freely propagating statistically planar flame and V-flame configurations with different turbulent Reynolds number Ret. The statistical behaviours of Nc and different terms of its trans...

LARGE EDDY SIMULATION OF A BLUFF BODY STABILIZED LEAN PREMIXED FLAME
The present study is devoted to verify current capabilities of Large Eddy Simulation (LES) methodology in the modeling of lean premixed flames in the typical turbulent combustion regime of Dry Low NOx gas turbine combustors. A relatively simple reactive test case, presenting all main aspects of turbulent combustion interaction and flame stabilization of gas turbine lean premixed combustors, was ch...

EXPERIMENTAL GASIFICATION OF BIOMASS IN AN UPDRAFT GASIFIER WITH EXTERNAL RECIRCULATION OF PYROLYSIS GASES
Theupdraft gasifier is a simple type of reactor for the gasification of biomass that is easy to operate and has high conversion efficiency, although it produces high levels of tar. This study attempts to observe the performance of a modified updraft gasifier. A modified updraft gasifier that recirculates the pyrolysis gases fromdrying zone back to the combustion zone and gas outlet at reduction zo...

MOVING BED GASIFICATION OF LOW RANK ALASKA COAL
This paper presents process simulation of moving bed gasifier using low rank, subbituminous Usibelli coal from Alaska. All the processes occurring in a moving bed gasifier, drying, devolatilization, gasification, and combustion, are included in this model. The model, developed in Aspen Plus, is used to predict the effect of various operating parameters including pressure, oxygen to coal, and steam...

PHYSICAL AND COMBUSTION CHARACTERISTICS OF BRIQUETTES MADE FROM WATER HYACINTH AND PHYTOPLANKTON SCUM AS BINDER
The study investigated the potential of water hyacinths and phytoplankton scum, an aquatic weed, as binder for production of fuel briquettes. It also evaluated some physical and combustion characteristics. The water hyacinths were manually harvested, cleaned, sun-dried, and milled to particle sizes distribution ranging from <0.25 to 4.75mm using hammer mill.The water hyacinth grinds and binder ...
