Experimental and numerical study of upward flame spread and heat transfer over expanded polystyrene at different altitudes

Case Studies in Thermal Engineering, 2021
Experimental and numerical study on upward, vertical flame spread was carried out on expanded polystyrene (EPS) at two different altitudes of 50 m and 3658 m to understand the effect that altitude has on flame spread of melted material.

Non-linear simulations of combustion instabilities with a quasi-1D Navier-Stokes code

, 2010
As lean premixed combustion systems are more susceptible to combustion instabilities than non-premixed systems, there is an increasing demand for improved numerical design tools that can predict the occurrence of combustion instabilities with high ...

Study of burner geometry effects on non-premixed flame response under acoustic excitation

Journal of Low Frequency Noise, Vibration and Active Control, 2019
The study of the flame under the acoustic excitation contributes to the study of flame self-excited thermoacoustic instability. Although non-premixed combustion is widely used in industry, research on its combustion instability characteristics is ...
