On construction of the canonical form on the frame bundle

open access: yesДифференциальная геометрия многообразий фигур, 2023
The detailed description of the construction of the canonical form on the higher order frame bundle over an n-dimensional smooth manifold is given. In particular, it is shown that some vector space isomorphism play­ing the key role in this construction ...

Numerical Study on the Effect of Jet on the Operation of Powder Fuel Scramjet [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
Metal powder fuel has high energy and volume calorific values, and it is an excellent power fuel for hypersonic aircraft in the future. However, metal powder has poor flow characteristics and is difficult to be effectively mixed with air when supersonic ...

A coupled conjugate heat transfer and CFD model for the thermal runaway evolution and jet fire of 18650 lithium-ion battery under thermal abuse

open access: yeseTransportation, 2022
: Thermal runaway (TR) is a major safety concern for lithium-ion batteries. A TR model incorporating the resulting jet fire can aid the design optimization of battery modules.

Event Horizon Telescope observations of the jet launching and collimation in Centaurus A [PDF]

open access: yesNature Astronomy, 2021
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimetre wavelengths have the power to reveal the launching and initial collimation region of extragalactic radio jets, down to 10–100 gravitational radii (rg ≡ GM/c2 ...

The anti-$k_t$ jet clustering algorithm [PDF]

open access: yes, 2008
The k_t and Cambridge/Aachen inclusive jet finding algorithms for hadron-hadron collisions can be seen as belonging to a broader class of sequential recombination jet algorithms, parametrised by the power of the energy scale in the distance measure.
