Unsteady RANS Simulation of High Reynolds Number Trailing Edge Flow
Unsteady vortex shedding at a trailing edge may cause pressure fluctuations and strong tonal noise which can have important consequences to the performance of marine and aeronautical type lifting surfaces. This paper presents data from unsteady RANS simulation of high Reynolds number trailing edge flow. It aims to identify and quantify dominant features of the trailing edge flow field over a tw...
متن کاملComputer Simulation of Ammonia Cold Shot Converter
A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...

Statistical Estimation of Turbulent Trailing Edge Noise
A new computational aeroacoustic model suitable for the prediction of turbulent airfoil trailing edge noise is presented. The method (known as the RANS based Statistical Noise Model or RSNM) combines numerically generated, mean turbulence information with a Green’s function for a semi-infinite half-plane to generate a far-field acoustic auto-spectrum. As a preliminary application of the method,...
