Unsteady behaviour of opposite impinging jets interaction in crossflow

open access: yesNihon Kikai Gakkai ronbunshu, 2016
A mixing of fuel with air in jet engine is studied by analyzing unsteady turbulent flow in a simplified flow channel which consists of the opposed jets in a cross-flow.

The bluff body stabilized premixed flame in an acoustically resonating tube: combustion CFD and measured pressure field [PDF]

open access: yes, 2009
The resulting limit cycle amplitude and frequency spectrum of a flame placed in a combustor of rectangular cross section is investigated. The partially premixed flame is stabilized on a bluff body placed in the upstream half of the combustor.

Nonlinear analysis of pressure oscillations in ramjet engines [PDF]

open access: yes, 1986
Pressure oscillations in ramjet engines have been studied using an approximate method which treats the flow fields in the inlet and the combustor separately. The acoustic fields in the combustor are expressed as syntheses of coupled nonlinear oscillators

Fuel‐Tanker Explosions: Characterization and Emission Factors for the Quantification of the Associated Air Emissions From Burnt Premium Motor Spirit and Liquefied Petroleum Gas in Nigeria

open access: yesEnergy Science &Engineering, Volume 14, Issue 1, Page 91-98, January 2026.
ABSTRACT This study investigated the combustion characterization of Petroleum Motor Spirit (PMS) and Liquefied Petroleum Gas (LPG) due to fuel tanker explosions in Nigeria using Aspen Plus software. The simulation characterized and determined the emission factors (EFs) of the associated emissions from explosions.
