Abstract
Here we present results from DNS of oscillating pipe flow at Re = 11500 and Wo = 13 using a fully developed turbulent flow field as initial condition and different length of the computational pipe domain. We found that the flow is conditionally turbulent for short and medium pipe domains, while the flow field completely laminarises in longer computational domains. This observation is discussed in more detail by comparing spatial power spectra, turbulence statistics and integral quantities of the resulting flow fields. We conclude that the critical maximum pipe length for this special scenario lies within 3.54D < L < 5D.
