Of course you will normally always use the same type of roughness. In the illustrated Exemplary embodiment are two different types of roughness in one section only for the sake of simplicity shown. The number of individual roughnesses between the respective rows of nozzles is can be selected according to the requirements for the turbulence required in each case.
