Paper Title:
Computational Analysis and Studies on Differential Ejector
  Abstract

Studies on differential ejector configuration have been carried out with a view to obtain the optimal entrainment of low pressure gas flow by injecting the motive gas at an appropriate pressure and angle of injection. The length of mixing has been kept constant in one case and varied in another to get results for optimal angle of ejection (between 0 to 90 degrees) for varying mass flow rates between 0.02kg/s and 0.08kg/s, stagnation pressures between 200kPa to 2500kPa and conduit diameter being 50mm. The predictions made are validated employing a versatile code Fluent in 2-d, viscous, turbulent flow formulation. Since the flow is supersonic, compressible form of SIMPLE algorithm is used along with a first order upwinding scheme for correctly predicting the properties inside the flow domain. Various curves have been plotted depicting variation of Mach number with angle of ejection and Mach number with mass flow rate for various pressures and angles of ejection.
