Biodiesel Development and Characterization for Use as a Fuel in Compression Ignition Engines
Tập 123 Số 2 - Trang 440-447 - 2001
Neat vegetable oils pose some problems when subjected to prolonged usage in CI
engine. These problems are attributed to high viscosity, low volatility and
polyunsaturated character of the neat vegetable oils. These problems are reduced
to minimum by subjecting the vegetable oils to the process of
transesterification. Various properties of the biodiesel thus developed are
evaluated and compared in ...
Heat Transfer Enhancement in Channels With Turbulence Promoters
Tập 107 Số 3 - Trang 628-635 - 1985
Repeated rib roughness elements have been used in advanced turbine cooling
designs to enhance the internal heat transfer. Often the ribs are perpendicular
to the main flow direction so that they have an angle of attack of 90 deg. The
objective of this investigation was to determine the effect of rib angle of
attack on the pressure drop and the average heat transfer coefficients in the
fully develo...
Fuel-Cooled Thermal Management for Advanced Aeroengines
Tập 126 Số 2 - Trang 284-293 - 2004
Fuel-cooled thermal management, including endothermic cracking and reforming of
hydrocarbon fuels, is an enabling technology for advanced aero engines and
offers potential for cycle improvements and pollutant emissions control in gas
turbine engine applications. The successful implementation of this technology
is, however, predicated on the use of conventional multicomponent hydrocarbon
fuels and ...
Hydrocarbon Fuel Cooling Technologies for Advanced Propulsion
Tập 119 Số 2 - Trang 344-351 - 1997
Storable hydrocarbon fuels that undergo endothermic reaction provide an
attractive heat sink for future high-speed aircraft. An investigation was
conducted to explore the endothermic potential of practical fuels, with
inexpensive and readily available catalysts, under operating conditions
simulative of high-speed flight applications. High heat sink capacities and
desirable reaction products have b...
Laminar Flame Speed and Ignition Delay Time Data for the Kinetic Modeling of Hydrogen and Syngas Fuel Blends
Tập 135 Số 2 - 2013
Laminar flame speeds and ignition delay times have been measured for hydrogen
and various compositions of H2/CO (syngas) at elevated pressures and elevated
temperatures. Two constant-volume cylindrical vessels were used to visualize the
spherical growth of the flame through the use of a schlieren optical setup to
measure the laminar flame speed of the mixture. Hydrogen experiments were
performed a...
Bayesian Network Approach for Gas Path Fault Diagnosis
Tập 128 Số 1 - Trang 64-72 - 2006
A method for solving the gas path analysis problem of jet engine diagnostics
based on a probabilistic approach is presented. The method is materialized
through the use of a Bayesian Belief Network (BBN). Building a BBN for gas
turbine performance fault diagnosis requires information of a stochastic nature
expressing the probability of whether a series of events occurred or not. This
information ca...
A New Bump-Type Foil Bearing Structure Analytical Model
Tập 129 Số 4 - Trang 1047-1057 - 2007
A gas bearing of bump foil type comprises an underlying structure made of one or
several strips of corrugated sheet metal covered by a top foil surface. The
fluid film pressure needs to be coupled with the behavior of the structure for
obtaining the whole bearing characteristics. Unlike in classical
elasto-aerodynamic models, a foil bearing (FB) structure has a very particular
behavior due to fric...
Measurement of Structural Stiffness and Damping Coefficients in a Metal Mesh Foil Bearing
Tập 132 Số 3 - 2010
Engineered metal mesh foil bearings (MMFBs) are a promising low cost bearing
technology for oil-free microturbomachinery. In a MMFB, a ring shaped metal mesh
provides a soft elastic support to a smooth arcuate foil wrapped around a
rotating shaft. This paper details the construction of a MMFB and the static and
dynamic load tests conducted on the bearing for estimation of its structural
stiffness ...
Overall Effectiveness of a Blade Endwall With Jet Impingement and Film Cooling
Tập 136 Số 3 - 2014
Ever-increasing thermal loads on gas turbine components require improved cooling
schemes to extend component life. Engine designers often rely on multiple
thermal protection techniques, including internal cooling and external film
cooling. A conjugate heat transfer model for the endwall of a seven-blade
cascade was developed to examine the impact of both convective cooling and solid
conduction thr...
Options in Gas Turbine Power Augmentation Using Inlet Air Chilling
Tập 113 Số 2 - Trang 203-211 - 1991
Gas turbine power augmentation in a cogeneration plant using inlet air chilling
is investigated. Options include absorption chillers, mechanical (electric
driven) chillers, thermal energy storage. Motive energy for the chillers is
steam from the gas turbine exhaust or electrical energy for mechanical chillers.
Chilled water distribution in the inlet air system is described. The overall
economics o...
