Puffing and Micro-Explosion Phenomena of Water Emulsion Fuels

SAE Technical Paper Series, 1986
<div class="htmlview paragraph">The puffing and micro-explosion phenomena have been observed and photographed in water and hydrocarbon blended fuels. Hexane, Decane, Tridecane. Hexadecane gasoline and diesel were tested as parent fuels at various percent by volume of water.

Prediction of micro-explosion delay of emulsified fuel droplets

International Journal of Thermal Sciences, 2009
Abstract Burning a water-in-oil emulsion enables reduction in solid and gaseous pollutants in comparison with neat oil. In the emulsion, Heavy Fuel-Oil and water lie in distinct phases, having a high difference in boiling point (up to 200 K). In an emulsion droplet injected and subsequently heated inside a flame, the internal water droplets are ...

Thermal Protection Capability of Micro-explosive Chamber for Micro-thruster Array

Proceedings of the 2nd International Conference on Artificial Intelligence and Advanced Manufacture, 2020
Accidental fire phenomenon, that the ignition of one microexplosive chamber element leads to that the adjacent ones are ignited, was a big problem for MEMS(Micro-Electro-Mechanical System)-based solid propellant micro-thruster arrays. In order to solve this problem, thermal protection capabilities of microexplosive chamber were modeled and simulated ...

Ultrafast-laser driven micro-explosions in transparent materials

Applied Physics Letters, 1997
We initiate micro-explosions inside fused silica, quartz, sapphire, and other transparent materials using tightly focused 100 fs laser pulses. In the micro-explosions, material is ejected from the center, forming a cavity surrounded by a region of compacted material.

The pit membrane changes of micro-explosion-pretreated poplar

Wood Science and Technology, 2016
A new technique, micro-explosion, was used to pretreat fast-growing poplar wood and improve membrane porosity. Poplar lumber with a thickness of 20 mm was pretreated 10 times at pressures of 0.4, 0.6, 0.8 and 1.0 MPa. Subsequently, the test and control groups were dried in air to equilibrium moisture content.

Thermonuclear micro-explosions with intense ion beams

Nature, 1974
HIGH density pellet compression may be important in laser fusion1. In this way the minimum energy input for breakeven can be substantially reduced to levels within reach of expected future laser technology. Further2 when this concept is applied to a fissionable pellet surrounded by a small neutron reflector, preferably TD, which is compressed together ...

Hollow Droplets Micro Explosive Thermal Spraying: Fundamentals

International Thermal Spray Conference, 2008
Abstract The peculiarities of plasma treatment of agglomerated YSZ powders as well as mechanically pretreated metal and metal alloy powder with the aim of their spheroidization and subsequent thermal spraying of produced HOSP powders are analyzed. Formation of splats from hollow droplets deserves a special attention for thermal spraying.

Micro-Explosion Modeling of Biofuel-Diesel Blended Droplets

SAE International Journal of Engines, 2011
<div class="section abstract"><div class="htmlview paragraph">Recently, with the increasing interest on some potential alternative substitutes of petroleum fuels such as biodiesel and butanol, more and more researches are focused on the field of bio-fuels because they are renewable and friendly to the environment and can possibly reduce ...

Density field visualization of a Micro-explosion using background-oriented schlieren

Journal of Visualization, 2013
The determination of flow field properties of large-scale explosions which is necessary for better understanding and flow modeling is rather challenging and difficult. Recent studies show that micro-explosions can be an acceptable substitute. However, quantitative determination of the flow field is still a challenge given the extremely short duration ...

Fluidized bed combustion of a diesel fuel: A modeling interpretation for micro-explosions

Proceedings of the Combustion Institute, 2007
Abstract The present paper deals with the combustion of liquid fuels in bubbling fluidized bed. The focus is on micro-explosions that were experimentally observed when burning a commercial bio-diesel in the intermediate temperature range 873–1023 K. The measured micro-explosions frequency fell in the range 2.4–3.8 Hz.
