Introduction

This tutorial considers the flow within a 2D, axisymmetric, co-rotating disk cavity system. Understanding the behavior of such flows is important in the design of secondary air passages for turbine disk cooling.

This tutorial demonstrates how to do the following:

• Set up a 2D axisymmetric model with swirl , using a rotating reference frame.

• Use the standard $k$- $\epsilon$ and RNG $k$- $\epsilon$ turbulence models with the enhanced near-wall treatment.

• Calculate a solution using the pressure-based solver.

• Display velocity vectors and contours of pressure.

• Set up and display XY plots of radial velocity and wall $y^+$ distribution.

• Restart the solver from an existing solution.
