[PDF][PDF] Role of intermittent dynamics in the onset of combustion instability

V Nair - 2014 - researchgate.net
Unsteady combustion in a confined, compressible flow-field can lead to the spontaneous
excitation of self-sustained periodic oscillations, provided the heat release rate fluctuations …

Dynamics of unsteady heat transfer and skin friction in pulsating flow across a cylinder

A Witte - 2018 - mediatum.ub.tum.de
The dynamic behavior of heat transfer and skin friction of a cylinder in pulsating crossflow for
small perturbations of flow velocity was investigated. In this regime, the time-averaged heat …
