Abstract - Numerical analysis was conducted to understand the combustion of Jet aviation gas in aircraft’s combustor. The study was aimed to conducted thermo-fluid analysis of Turbo-Union RB Engine combustor and the approach has been made using the application of CFD tool Ansys As combustion process is theFile Size: KB. each air entry port along the length of the are also obtained on the liner airflow distribution, and the static and total pressures in the annuli and liner along the length of the combustor. The data were obtained for assigned values of combustor geometry and operating con­ ditions by using the computer program developed in references 1and Size: 2MB.

  Safety of the appliance should be the primary goal of all technicians. The production of carbon monoxide (CO) in the flue gases should be kept below ppm air-free, even though the allowable limit in the stack is ppm : Jim Bergmann. The analysis presented attempts to establish the manner in which pulse combustion burner performance is influenced by the principal design parameters (combustion chamber volume, exhaust pipe length and diameter, gas valve flow parameters and air/fuel ratio). The analytical model developed defines. This paper describes design study of the gas turbine engine using PDE as a main combustor of which hydrogen is used as a fuel. In the present analysis, exhaust gas condition of the simple PDE in which no turbine or other obstacles are installed which is estimated by CFD is referred as a turbine inlet by: The HyShot II scramjet, shown in Figure 1, was designed to demonstrate supersonic combustion during flight in a simple configuration [17,40], and it has since been the subject of multiple ground.

combustor liner with the inlet mass flow rates being derived from 1D flow network analysis and used as boundary conditions for the internal-flow-only combustor CFD prediction. Although strongly coupled in reality, the two regions have rarely been coupled in CFD modelling for industrial applications.
