               1.1     Turbulent Channel Flow

               1.1.1    Prerequisites

                   • TransAT

                   • TransATUI

                   • Paraview (or Tecplot)

               1.1.2    Problem Description

               Single-phase flow with heat transfer through a channel is studied. The walls of the channel are
               kept at a constant temperature of 320 K. Air flows in through an inlet at a velocity of 3 m/s
               and an initial temperature of 300 K. The aim is to get a steady-state solution of the temperature
               profile in the channel. Since the flow is in the turbulent regime, k- turbulence model is used.


               1.1.3    Problem Setup
               The problem is setup in 2D.

                   • Domain: 1 m × 10 cm resolved by a mesh of 40 × 20 × 1 cells.

                   • Left: inflow: velocity 3.0 m/s, constant velocity inflow, temperature T in = 300 K.

                   • Right: outflow (velocity extrapolation)

                   • Y faces: no–slip walls, temperature T w = 320 K.
                   • Z faces: symmetry boundaries.
