The outbreak of 2019 novel coronavirus (2019-nCoV) pneumonia was reported in Wuhan, Hubei Province, China December and has spread internationally. This article discusses how radiology departments can most effectively respond to this public health emergency. On January 31, 2020, the World Health Organization declared a new as "Public Emergency International Concern (PHEIC)." February 13, officially named 2019-nCoV Corona Virus Disease-2019 Geneva, Switzerland. virus rapidly various cities...
The phenomenon of a hollow droplet impacting on solid surface is widely found in various fields. dynamic characteristics diesel droplets are studied by combining numerical simulation and theoretical analysis. contact angle model presented this paper couples the advantages existing models for simulating both spreading retracting stages. It also considers continuous variation during maximum state. Compared to models, error has been reduced from 14.9% 4.6%. effects impact velocity, angle,...
Cavitation generated during injector jetting can significantly affect fuel atomization. Laser-induced cavitation bubble is an important phenomenon in laser induced plasma ignition technology. Limited by the difficulties experimental measurements, numerical simulations have become tool study of laser-induced bubble, but most previous models used to dynamics usually ignore effect chemical reactions. In this study, finite volume method solve compressible two-dimensional reynolds averaged...
Taking the liquid-centered gas–liquid coaxial centrifugal nozzle as research subject, this study employs Gerris software to implement a combination of methods including interface tracking, grid adaptation, turbulence direct numerical simulation, and simulation both internal external flow fields. The examines atomization mechanisms characteristics under influence airflow co-rotating airflow, well counter-rotating airflow. It is observed that reduces radial extent spray field extends axial...
Liquid–solid two-phase flows are a very important class of multiphase flow problems widely existing in industry and nature. This paper establishes model for liquid–solid considering states granular media. The volume fraction is defined by the solid phase, determining material properties two phases, momentum exchanged between phases drag pressure gradient forces. On this basis, two-particle method simulating proposed coupling smoothed particle hydrodynamics with discrete hydrodynamics....
Summary This paper describes a novel methodology that combines smoothed discrete particle hydrodynamics (SDPH) and finite volume method (FVM) to enhance the effective performance in solving problems of gas‐particle multiphase flow. To describe collision fluctuation particles, this also increases new parameter, namely, granular temperature, according kinetic theory The coupled framework SDPH–FVM has been established, which drag force pressure gradient act on SDPH particles momentum sources...
In the storage areas of petrochemical industry, stored materials are flammable and explosive, layout tank farm is relatively tight that may lead to fire, explosion even domino accident. To analyze effect pool fire in farm, Bayesian network introduced coupling effects taken into account. Based on above theory, propagation patterns occurrence probability accident at first level second a specific 2*2 obtained. The posterior probabilities after considering new information calculated by Netica...
In this paper, the corrective continuity equation proposed by Ott and momentum improved Adami combine to solve two-dimensional simulation problems of droplet collisions in air. To effectively improve calculation accuracy, artificial viscosity stress are derived which suited for multi-phase flows with large density differences. This method is validated be effective via examples an initially square under surface tension evolution process two droplets Droplet different Weber numbers (8.8, 19.8)...
To overcome the drawback of discrete particle model (DPM) and Euler-Euler two-fluid (TFM) in solving gas-solid two phase flow, a new method called SPH-FVM coupled is presented, then it used to simulate aerolian sand transport problems. Based on pseudo fluid smoothed hydrodynamics (SPH) solve by tracing movement each individual particle, finite volume (FVM) discretize continuum flow field stationary mesh capturing characteristics. Two phases are through contributions due effects drag,...
A fuel air cloud is formed under the driving force of explosive detonation and then it’s ignited to explosion attack target. The existing numerical simulations are mainly limited dispersal processes which all based on mesh methods. particles in difficult traced. Otherwise, computing process complex could not be solved by exiting methods for chemical reaction forming propagation shock waves both involved combustion explosion. Smoothed discrete particle hydrodynamics (SDPH), as a new method...
A fatal transfusion reaction due to anti-Ku in a Knull (Ko) patient is reported. The was transfused with 34 units of incompatible RBCs during 44 days hospitalization. Apart from the first transfusion, all subsequent transfusions failed raise patient's Hb. No serum antibody identified until he transferred another hospital for dialysis. compatibility test demonstrated weak and autocontrol reacting at room temperature by manual polybrene method. considered be "cold agglutinin." blood sample...
Heat transfer between particles and that gas phase particle in gas-particle two-phase flow cannot be ignored.
