Physics of puffing and microexplosion of emulsion fuel droplets [PDF]

, 2014
The physics of water-in-oil emulsion droplet microexplosion/puffing has been investigated using high-fidelity interface-capturing simulation. Varying the dispersed-phase (water) sub-droplet size/location and the initiation location of explosive boiling ...

Experimental Investigation on the High-frequency Pressure Oscillation Characteristics of a Combustion Process in a DI Diesel Engine

Energies, 2020
It is difficult to decompose the in-cylinder pressure of combustion of the direct injection (DI) diesel engine, a transient process associated with complicated oscillation components, because of its steep property. An adaptive cyclic average method based

Utilization of Combustion-Driven Oscillations [PDF]

The Journal of the Acoustical Society of America, 1963
The possible applications of combustion-driven oscillations fall into two categories. The first category includes applications that are related to the combustion process itself, such as those concerned with the possibility of alterlog space heat-release rate, combustion efficiency, heat transfer to surfaces, and agglomeration of solid or liquid ...

Numerical study of acoustic oscillations and combustion instabilities in solid propellant rocket [PDF]

, 1997
A numerical analysis of unsteady motions in solid rocket motors has been conducted. A fully coupled implicit scheme based on a dual time-stepping integration algorithm has been adopted to solve the governing equations and associated boundary conditions.

Reduced-order modeling and dynamics of nonlinear acoustic waves in a combustion chamber [PDF]

, 2005
For understanding the fundamental properties of unsteady motions in combustion chambers, and for applications of active feedback control, reduced-order models occupy a uniquely important position. A framework exists for transforming the representation of

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.
