RISLarge Eddy Simulation With Zonal Near Wall Treatment of Flow and Heat Transfer in a Ribbed Duct for the Internal Cooling of Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large eddy simulations of flow and heat transfer in a square ribbed duct with rib height to hydraulic diameter of 0.1 and 0.05 and rib pitch to rib height ratio of 10 and 20 are carried out with the near wall region being ...
Reynolds Averaged Navier–Stokes and Large Eddy Simulation Investigation of Lean Premixed Gas Turbine Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reynoldsaveraged Navier–Stokes (RANS) and largeeddy simulations (LES) of a Siemens scaled combustor are compared against comprehensive experimental data. The steady RANS simulation modeled one quarter of the geometry ...
Investigation of Single Jet Combustor Near Lean Blowout Conditions Using Flamelet Generated Manifold Combustion Model and Detailed Chemistry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical simulation results of a singlejet premixed combustion system at atmospheric pressure are compared against comprehensive particle image velocimetry (PIV) flow measurements and Raman scattering temperature measurements ...
