Numerical analysis of flow around infinite cylinders at trans-critical Raynolds number

Original language description

This paper examines the flow field and pressure distribution around an infinite cylinder in the trans-critical flow regime using the k-ε RANS turbulence model. ANSYS Fluent, finite volume solver is used for numerical investigation of wind induced pressure load on finite cylinders. A steady state 2-D Fluent model is used with changing various modelling parameters on the static pressure distribution around the infinite cylinder. These parameters include surface roughness, modelled by two different techniques by physical modelling wind ribs and equivalent sand roughness, and cylinder rotation at the cylinder surface. The main objective is to find suitable parameter, which can be used for accurate adjustment of the pressure distribution around the cooling tower, which allows better sensitivity analysis and modelling of the performance of cooling towers for wind conditions with and without meridional ribs disposed on the outer surface of the shell.
