The Quiescent Combustion Chamber

Journal of Fluids Engineering, 1931
Abstract The term “quiescent” is originated as describing more accurately than “non-turbulent” the condition of the combustion chamber in some fuel-injection engines at the time of injection of the fuel. Such a combustion chamber is considered quiescent if the movement of the air has no appreciable effect on the distribution of the fuel ...

Combustion stability of a dispersed fuel in a combustion chamber

Journal of Engineering Physics, 1968
A combustion instability criterion and an analogy with the burning of a solid propellant element are established as a result of an analysis of the behavior of the gasdynamic disturbances superimposed on the process of turbulent combustion of an atomized fuel in a one dimensional combustion chamber.

Relationship Between Combustion Chamber Deposits, Fuel Composition, and Combustion Chamber Deposit Structure

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">This study investigated the relationship between the average molecular structures of combustion chamber deposits (CCD), the quantity of deposit formed and the aromatic content of the fuel. Solid-state ¹³C nuclear magnetic resonance (NMR) techniques developed for the study of coal were applied
