On construction of the canonical form on the frame bundle
Дифференциальная 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]
Journal 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 ...

Communications in Nonlinear Science and Numerical Simulation, 2003 The problem of characterizing the origin of the non-Gaussian properties of transport resulting from Hamiltonian dynamics is addressed. For this purpose the notion of chaotic jet is revisited and leads to the definition of a diagnostic able to capture some singular properties of the dynamics.

Disentangling jet modification in jet simulations and in Z+jet data
Journal of High Energy Physics, 2022 AbstractThe selection of jets in heavy-ion collisions based on theirpTafter jet quenching is known to bias towards jets that lost little energy in the quark-gluon plasma. In this work, we study and quantify the impact of this selection bias on jet substructure observables so as to isolate effects caused by the modification of the substructure of jets ...

Flow characteristics of multiple round jets with square arrangement
Nihon Kikai Gakkai ronbunshu, 2022 The present paper describes the flow characteristics of multiple round air jets with square arrangement at a relatively low-Reynolds number (Re = 4.1×103). The diameter of a round nozzle was d = 6 mm.
