CASE STUDY:FLOW AROUND A CYLINDER

• Characteristic length scale: D (cylinder diameter)

• Model the flow as 3-D but with one element through the thickness and symmetry boundary conditions on the front and back faces to enforce 2-D conditions

11


Create a “CFD” model in Abaqus/CAE

12


Define a part representing the flow domain

13


Generate the mesh

14


Define fluid material propertiesNewtonian fluid• Density: 1000 kg/m3• Viscosity: 0.1 Pa.sec

Properties are chosen to set the flow Reynolds number at 100 based on cylinder diameter

15


Create and assign a fluid section and instance the part

16


Define an incompressible flow analysisTransient analysis

17


18


Primary solution quantities• Velocity components• Pressure

19


Laminar or turbulent flow• Laminar flow (default)• Choice of turbulence models

20


Request output variables

21


Define boundary conditions
