Time-resolved gas temperatures in the oscillating turbulent flow of a pulse combustor tail pipe

Pulse Combustor Tail-Pipe Heat-Transfer Dependence on Frequency, Amplitude, and Mean Flow Rate

A commonly cited advantage of pulse combustors is a high rate of heat transfer in the tail pipe. Past research on these rates of heat transfer is inconclusive regarding the amount of heat transfer enhancement and how various flow parameters affect this enhancement. This article reports an experimental heat transfer study in the tail pipe of a pulse combustor. The pulsation frequency, pulsation ...

Manipulating Flow Structures in Turbulent Pipe Flow

Two different tools, the non-empirical resolvent analysis and the data-based dynamic mode decomposition, are employed to assess the changes induced by transpiration in the dynamics of a turbulent pipe flow. The focus is on very large-scale motions. Both analyses permit the observation of streamwise waviness in the large flow structures and how the transpiration can inhibit fluctuation in locali...

A Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid

The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced <span style="font-size: 10pt...
