in this research, the frequency of the jet streams associated with extreme and pervasive precipitation has been analyzed using environmental to circulation approach. based on the 99th percentile index, 109 days of the extreme and pervasive precipitation was selected from the irimo data base ( including 33 synoptic, climatic and rain gage stations during 15992 days from farvardin, 1st, 1340 to d...

numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. however, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. the present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle level. a...

Azimuthal correlations in Z+jet production at large transverse momenta are computed by matching Parton - Branching (PB) TMD parton distributions and showers with NLO calculations via MCatNLO. The predictions compared those for dijet the same kinematic range. azimuthal $\Delta\phi$ between Z boson leading jet steeper to ${\cal O}(100)$ GeV, while they become similar very high O}(1000)$ GeV. diff...

Due to the opaqueness of rock and limitation detection technology, it is impossible accurately describe crack growth process determine law breakage. Based on smoothed particle hydrodynamics finite element method (SPH-FEM), a numerical model for high-speed water jet breaking was established in this work simulate fragmentation impacted by jet, study effects different angles propagation microscopi...

A plane subsonic jet was subjected to periodic oscillations in the near nozzle region by a twin vane system. During excitation, the jet was found to spread significantly and entrain mass much more than its steady counterpart. Time averaged static pressure measured in the flow field with a disc probe exhibited prominent well defined suction regions different from that of a steady jet.

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

This study examines the mass and Lagrangian transport, kinematic dynamic characteristics of shallow-water breaking waves, focusing on wave breaking, jet impingement processes. A multiphase Navier–Stokes flow model has been developed to track origin trajectory for splash-up using both a geometric piece-wise linear interface calculation volume-of-fluid (PLIC-VOF) particle tracking approaches. The...

Electroweak symmetry breaking can be a consequence of color sextet quark chiral symmetry breaking, with sextet pions producing the longitudinal components of the electroweak vector bosons. If so, a special solution of QCD is involved, for which the high-energy S-Matrix can be constructed “semiperturbatively” via the chiral anomaly and reggeon diagrams. An infra-red fixed point and the starting ...
