Numerical simulation on H2S distribution characteristics of tangentially coal-fired boiler under wide loads

open access: yesMeitan xuebao
Air staged combustion reduces NOx emissions, but increases the H2S concentration in primary combustion zone. The excessive H2S concentration near the furnace wall is an important factor that aggravates the high-temperature corrosion of the water-cooled ...

Study of triangular flow $v_3$ in Au+Au and Cu+Cu collisions with a multiphase transport model

open access: yes, 2012
We studied the relation between the initial geometry anisotropy and the anisotropic flow in a multiphase transport model (AMPT) for both Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV.

Partonic Effects in Heavy Ion Collisions at RHIC

open access: yes, 2002
Effects of partonic interactions in heavy ion collisions at RHIC are studied in a multiphase transport model (AMPT) that includes both initial partonic and final hadronic interactions.It is found that a large parton scattering cross section is needed to ...

A multi-physics methodology for the simulation of the two-way interaction of reactive flow and elastoplastic structural response

open access: yes, 2017
We propose a numerical methodology for the numerical simulation of distinct, interacting physical processes described by a combination of compressible, inert and reactive forms of the Euler equations, multiphase equations and elastoplastic equations ...

Chemical-looping combustion characteristics of Zhundong coal semicoke with hematite oxygen carrier and transformation of alkali and alkaline earth metals

open access: yesMeitan xuebao
The low-carbon, clean, and efficient utilization of the Zhundong coal is greatly limited by some severe problems such as ash accumulation, slagging, and CO2 emissions in the conventional combustion and utilization processes. The adoption of low-rank coal

Sand transport in multiphase flow mixtures in a horizontal pipeline: An experimental investigation

open access: yesPetroleum, 2019
An inherent problem with both oil and natural gas production is the deposition of sand particles in pipeline, which could lead to problems such as excessive pressure drops, equipment failure, pipeline erosion, and production decline. The characterization

Mathematical Modeling of Multiphase Flow in Steel Continuous Casting

open access: yesISIJ International, 2019
In continuous casting of steel, multiphase flow arises in many different ways.1) Argon gas is often injected into the molten steel, usually through the upper tundish nozzle walls2,3) or stopper rod tip.4) This is beneficial to avoid clogging5) and air ...
