Page 11.144.1 Page © American Society for Engineering Education, 2006 A Web-based Solver for Compressible Flow Calculations Abstract Compressible flow is an important subject in aerospace and mechanical engineering disciplines. This paper describes a web-base solver for carrying out compressible flow calculations. The main objective of the solver is to provide students with a software tool than can be used in the compressible flow course offered in the Department of Mechanical Engineering at Lamar University. The solver has a graphical user interface (GUI) for ease of use and interactivity. The solver is capable of solving typical compressible flows such as isentropic flows, Rayleigh and Fanno flows, normal and oblique shock flows, and Prandtl-Myer expansion waves.

  • SPC 407 Sheet 5 - Solution Compressible Flow – Rayleigh Flow
    SPC 407 Sheet 5 - Solution Compressible Flow – Rayleigh Flow 1. Consider subsonic Rayleigh flow of air with a Mach number of 0.92. Heat is now transferred to the fluid and the Mach number increases to 0.95. Does the temperature T of the fluid increase, decrease, or remain constant during this process? How about the stagnation temperature T0? Solution: In Rayleigh flow, the stagnation temperature T0 always increases with heat transfer to the fluid, but the temperature T decreases with heat transfer in the Mach number range of 0.845 < Ma < 1 for air. Therefore, the temperature in this case will decrease. This at first seems counterintuitive, but if heat were not added, the temperature would drop even more if the air were accelerated isentropically from Ma = 0.92 to 0.95. 2. Consider subsonic Rayleigh flow that is accelerated to sonic velocity (Ma = 1) at the duct exit by heating. If the fluid continues to be heated, will the flow at duct exit be supersonic, subsonic, or remain sonic? Solution: The flow is choked, and thus the flow at the duct exit remains sonic. There is no mechanism for the flow to become supersonic in this case. 1 3. Argon gas enters a constant cross-sectional area duct at Ma1 = 0.2, P1 = 320 kPa, and T1 = 400 K at a rate of 1.2 kg/s. Disregarding frictional losses, determine the highest rate of heat transfer to the argon without reducing the mass flow rate. Solution: Take the properties of argon to be k = 1.667, cp = 0.5203 kJ/kg-K, and R = 0.2081 kJ/kg-K.

Disregarding frictional losses, determine the highest rate of heat transfer to the argon without reducing the mass flow rate. 4. Air is heated as it flows subsonically through a duct. When the amount of heat transfer reaches 67 kJ/kg, the flow is observed to be choked, and the velocity and the static pressure are measured to be 680 m/s and 270 kPa. Disregarding frictional losses, determine the velocity, static temperature, and static pressure at the duct inlet. 5. Compressed air from the compressor of a gas turbine enters the combustion chamber at T1 = 700 K, P1 = 600 kPa, and Ma1 = 0.2 at a rate of 0.3 kg/s. Via combustion, heat is transferred to the air at a rate of 150 kJ/s as it flows through the duct with negligible friction.
