Flame Phenomenology for Premixed Methane and Propane/Air in Developed Meso-scale Channels at Ambient Conditions
Abstract: This paper reports the development of a meso-scale channel for propagation of methane and propane-air mixtures at low Reynolds number. An experiment was conducted in 3, 4 and 5 mm internal quartz tube diameters at premixed conditions of the fuel/air. The tubes were vertically mounted and sometimes preheated uniformly laterally. Uniformly laterally heating gives a zero temperature gradient. Flame phenomenology at different equivalence ratios (φ) of the mixture was discussed. …

THE STUDY OF BURNING CHARACTERISTICS OF AP/HTPB/AL BASIC COMPONENTS OF A COMPOSITE PROPELLANT
Abstract: Starting the research on a solid propellant would be very much easier if the burning characteristics of a simple propellant is known. A simple propellant is a propellant made of three basic components namely oxidizer, fuel and binder without any additive substance to alter its characteristics. Unfortunately, a very limited number of references were published discussing the burning characteristics of simple propellant. This paper describes the burning characteristics of basic …

CI Engine Modeling Techniques
Abstract: The internal combustion engine is a heat engine that converts chemical energy in a fuel into mechanical energy, usually made available on a rotating output shaft. Internal combustion engines can be classified in many ways primarily by the type of ignition system they use, spark ignition (SI) and compression ignition (CI). An SI engine starts the combustion process in each cycle by use of a spark plug. The spark plug …

Numerical Simulation of Air Flow Field of A Gas Turbine Engine Air blast Atomizer
Abstract: One of the most crucial process that occurs before the fuel is burned in the combustion chamber is atomization. The performance of a engine will be depend mainly on the fuel mixture. Performance of the engine depends on atomization process because it breaks the bulk fuel into small droplets and injects it into the combustion chamber, in order to make this happen consequently the dimensions of most of the fuel …
