In a rocket engine, the propellants are injected into the combustion chamber at high pressures and burned at high temperatures. This combination of high pressure and high temperature is the reason why rocket design is so difficult to do well. Combustion chambers must be designed to ensure stable combustion of the fuel injected and optimum fuel utilization within the limited space available and over a large range of air/fuel ratios. In a gas turbine engine, the combustor is fed by high pressure air by the compression system. Overall design of the combustion chamber will determine how great the effect of reducing quench will be. Overall design includes the chamber area in the cylinder head as well as the piston which makes up the lower portion of the combustion chamber. Combustion Chamber A parameter describing the chamber volume required for complete combustion is the characteristic chamber length, L*, which is given by Where Vcis the chamber volume (including the converging section of the nozzle), in cubic inches, and Atis the nozzle throat area (in2).

This paper presents the design of combustion chamber followed by three dimensional simulations to investigate the The design of Can-type combustion chamber, modified can -type combustion chamber geometry and numerical investigations is carried out. The k-ω model used for analysis and also the mean temperature, reaction rate, and velocity fields are almost insensitive to the grid size. Numerical investigation on Can-type combustion chamber and a modified The design and analysis of gas turbine combustion chamber is based on combined theoretical and empirical approach and the design of combustion chamber is a less than exact science. This paper presents the design of combustion chamber followed by three dimensional simulations to investigate the Direct Injection type combustion chambers are also known as the open type combustion chambers. This open type combustion chambers, the combustion chamber volume will be located in the cylinder.

Quench is most effective with wedge chambers and flat-top pistons. Combustion chamber design is an important factor in an engine’s particulate emission. Designers can make use of air motion turbulence at the piston and cylinder wall to prevent fuel impingement upon the wall and piston top. The design of a combustion chamber and the method of adding the fuel may vary considerably, but the airflow distribution used to effect and maintain combustion is always very similar to that described. The combustion chamber design time shape of combustion chamber, location of spark plug, valve position, combustion chamber size this all point is considered and when this all condition is satisfied then combustion chamber used in ic engine.the good combustion chamber requirement is as follows.
