Title of Document : HOMOGENEOUS AND HETEROGENEOUS SENSORS FOR COMBUSTION SYSTEMS

Title of Document: HOMOGENEOUS AND HETEROGENEOUS SENSORS FOR COMBUSTION SYSTEMS Amir Eshaghi, PhD, 2012 Directed By: Distinguished University Professor, Professor Ashwani K. Gupta, Department of Mechanical Engineering Due to increasingly stringent emission regulations, it is important to develop clean combustors. Combustion behavior is very complex in almost all practical power plant systems. M...

Combustion and Emission of a Compression Ignition Engine Fueled with Diesel and Hydrogen-Methane Mixture

The present study conducted experimental investigation on combustion and emission characteristics of compression ignition engine using diesel as pilot fuel and methane, hydrogen and methane/hydrogen mixture as gaseous fuels at 1800 rev min. The effect of gaseous fuel on peak cylinder pressure and heat release is modest at low to medium loads. At high load, the high combustion temperature and hi...

Catalytic Combustion of Biogas-Hydrogen Mixtures in a Packed Bed Reactor

Low Pressure Catalytic Combustion of Hydrogen on Palladium

Exhausts of airship fabric bag in the stratosphere such as hydrogen which can be used for fuels by using catalytic combustion method. This can save the extra fuels used in the power system. Pd/γAl2O3 catalyst was prepared in this work by impregnation method and the H2 catalytic combustion reaction kinetic was investigated between the pressure of 3.6 kPa and 101.3 kPa. The effects of temperature...

A CFD Simulation of Hydrogen Production in Microreactors

In this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. The catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3D geometry for the microreactor. To calculate diffusion among species, mixture average correlations are compared to Stephan-Maxwell equations. The reactions occurring in...
