RISIsothermal Boundary Condition at Casing Applied to the Rotor 37 Transonic Axial Flow Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) simulations are presented with an isothermal boundary condition at the casing for running NASA Rotor 37. The casing temperature is set to the inlet total temperature. Relative to the ...
Numerical Modeling and Design Challenges of Boundary Layer Ingesting Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Studies show that boundary layer ingesting (BLI) propulsion can provide significant fuel burn reduction relative to pylon-mounted turbofan engines. However, this type of propulsion can lead to serious difficulties and ...
Experimental Study of the Real Gas Effects of CO2 on the Aerodynamic Performance Characteristics of a 1.5-Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermodynamic properties of CO2 do not obey the ideal gas law and the simplified equation of state. The enthalpy and sonic speed depend on both temperature and pressure whereas the enthalpy and the speed of sound of ...
