Nonlinear analytical flame models with amplitude-dependent time-lag distributions (2018)
Journal Article
Heckl. (2018). Nonlinear analytical flame models with amplitude-dependent time-lag distributions. International Journal of Spray and Combustion Dynamics, 264-276. https://doi.org/10.1177/1756827717728056

In the present work, we formulate a new method to represent a given Flame Describing Function by analytical expressions. The underlying idea is motivated by the observation that different types of perturbations in a burner travel with different speed...

Passive control of instabilities in combustion systems with heat exchanger (2018)
Journal Article
Surendran, A., Heckl, M. A., Hosseini, N., & Jan Teerling, O. (2018). Passive control of instabilities in combustion systems with heat exchanger. International Journal of Spray and Combustion Dynamics, 10(4), 362 -379. https://doi.org/10.1177/1756827717731486

One of the major concerns in the operability of power generation systems is their susceptibility to combustion instabilities. In this work, we explore whether a heat exchanger, an integral component of a domestic boiler, can be made to act as a passi...

Aeroacoustic response of an array of tubes with and without bias-flow (2018)
Journal Article
Surendran, A., Heckl, M. A., Peerlings, L., Boij, S., Bodén, H., & Hirschberg, A. (2018). Aeroacoustic response of an array of tubes with and without bias-flow. Journal of Sound and Vibration, 454, 1 -16. https://doi.org/10.1016/j.jsv.2018.07.022

Heat exchangers, consisting of tube arrays in a cross-flow are a vital component of power generation systems. They are of interest from an acoustic point of view, because they can reflect, transmit and absorb an incident sound wave; in other words, t...
