Client Profile.

Jet engine designer & manufacturer, USA
Industry: Automotive Industry


A leading designer and manufacturer of jet engines had to validate the designs by studying the reacting flow by analyzing air-fuel mixture to attain optimum A-F ratio. HitechDigital CFD specialists simulated the flow patterns and combustion process using ANSYS Fluent to deliver the flow results and study outcomes for the manufacture in design modification – if need be.

Business Needs.

  • Determination of optimum value of air-fuel ratio.
  • Analyse various gases formation inside the combustor by combustion process.
  • Measure the efficiency of jet engine and devise reliable performance with design optimization.
  • Analyze the combustible pollutants i.e. CO2, NOx, soot, etc. during combustion.


  • Creating and simulating reactive mixture of the fuel and air.
  • Developing correct model for mesh with cut out outer wall for studying air flow.
  • As combustion analysis needs expertise, it consumes extra time putting the CFD specialist under peer pressure of meeting deadlines.
  • Simulating multiple values of air and fuel flow rates.
