Bubble Growth as a Detonation [PDF]

open access: yes, 1993
Bubble growth as a detonation is studied in the context of cosmological phase transitions. It is proved that the so called Chapman-Jouguet hypothesis, which restricts the types of detonations that can occur in spherically symmetric chemical burning, does

A Numerical Study on the Flow Characteristics and Flow Uniformity of Vanadium Redox Flow Battery Flow Frame

open access: yesApplied Sciences, 2020
As the demand for electrical energy increases worldwide, the amounts of harmful gases in the atmosphere, such as carbon dioxide released by burning fossil fuel, are continuously increasing. As a result, the interest in renewable energy resources has been

Some Properties of Concrete Containing High Fraction Volume of Metakaolin [PDF]

open access: yesEngineering and Technology Journal, 2014
In this research, a study has been made on the effect of high fractional volume of replacement Metakaolin that results from grinding and burning the local kaolin from (Doeakhla zone / west of Baghdad / Iraq) with fineness of 18000 cm2/gm., and with ...

Effects of fresh gas velocity and thermal expansion on the structure of a Bunsen flame tip [PDF]

open access: yes, 2010
Numerical computations and order-of-magnitude estimates are used to describe the tip region of a Bunsen flame where the flame departs from a planar flame at an angle to the incoming fresh gas flow.

Thermonuclear Burning on the Accreting X-Ray Pulsar GRO J1744-28 [PDF]

open access: yes, 1996
We investigate the thermal stability of nuclear burning on the accreting X-ray pulsar GRO J1744-28. The neutron star's dipolar magnetic field is 50 years.

An experimental study on promotion of burning velocity of powder-gas hybrid combustion in a stagnation-point flow

open access: yesNihon Kikai Gakkai ronbunshu
An experimental study was made on burning velocity in powder-gas hybrid combustion in order to investigate the determination factor to alter the burning velocity caused by the addition of power in the premixed gas.

Low Carbon Abundance in Type Ia Supernovae

open access: yes, 2006
We investigate the quantity and composition of unburned material in the outer layers of three normal Type Ia supernovae (SNe Ia): 2000dn, 2002cr and 20 04bw.

A mechanism for high-frequency oscillation in ramjet combustors and afterburners [PDF]

open access: yes, 1956
An experimental investigation was made of the behavior of a small two-dimensional combustion chamber, burning a uniform mixture of air and fuel vapor under conditions of high-frequency oscillation or screech.

Small-scale Interaction of Turbulence with Thermonuclear Flames in Type Ia Supernovae [PDF]

open access: yes, 1999
Microscopic turbulence-flame interactions of thermonuclear fusion flames occuring in Type Ia Supernovae were studied by means of incompressible direct numerical simulations with a highly simplified flame description.
