Abstract

Experimental evidence suggests that the laminar state in a circular pipe flow can be achieved over a wide range of flow rates or Reynolds numbers. However there are many aspects of the stability of developing pipe flow problem related to the inlet flow conditions and the entrance length that should be clarified. The axial position for the onset of wall turbulence in the case of natural transition will be measured for a large range of Reynolds numbers. After that, the purpose of this investigation is to take advantage of the CoLaPipe to test the effect of perturbations and the development of high Reynolds number flow.
