A modified particle method for semilinear hyperbolic systems with oscillatory solutions [PDF]

, 2004
We introduce a modified particle method for semi-linear hyperbolic systems with highly oscillatory solutions. The main feature of this modified particle method is that we do not require different families of characteristics to meet at one point.

Maximizing the energy efficiency of induced draft and hybrid draft cooling towers

Case Studies in Thermal Engineering
Cooling towers consume energy in the order of several hundred kilowatts for operating fans and pumps for driving air and water through the tower. Therefore, it is financially advantageous and environmentally friendly to optimize the fan operation of a ...

Baryon number fluctuations in quasi-particle model

European Physical Journal C: Particles and Fields, 2017
Baryon number fluctuations are sensitive to the QCD phase transition and the QCD critical point. According to the Feynman rules of finite-temperature field theory, we calculated various order moments and cumulants of the baryon number distributions in ...

Event-by-Event Fluctuations of Particle Ratios in Heavy-Ion Collisions

, 2006
We study event-by-event dynamical fluctuations of various particle ratios at different energies. We assume that particle production in final state is due to chemical equilibrium processes.

A new tow-parameter integrable model of strongly correlated electrons with quantum superalgebra symmetry

, 1997
A new two-parameter integrable model with quantum superalgebra $U_q[gl(3|1)]$ symmetry is proposed, which is an eight-state electron model with correlated single-particle and pair hoppings as well as uncorrelated triple-particle hopping.

Simulation of Miniature PDMA for Ultrafine-Particle Measurement

Atmosphere, 2019
The effect of the design and process parameters of a particle-classification zone on the sizing precision of a plate differential mobility analyzer (PDMA) was investigated by simulation software in this work. The design parameters consisted of the length,

A thermodynamically consistent quasi-particle model without temperature-dependent infinity of the vacuum zero point energy

, 2012
In this paper, an improved quasi-particle model is presented. Unlike the previous approach of establishing quasi-particle model, we introduce a classical background field (it is allowed to depend on the temperature) to deal with the infinity of thermal ...

Discrete Element Modeling and Simulation of Soybean Seed Using Multi-Spheres and Super-Ellipsoids

IEEE Access, 2020
The accuracy of particle shape characterization is the key to the study of particle dynamics. This study proposes two modeling methods, super-ellipsoid approach (SE) and multi-sphere approach (MS), to describe the discrete element method (DEM) model of ...

Finite-temperature phase structures of hard-core bosons in an optical lattice with an effective magnetic field

, 2012
We study finite-temperature phase structures of hard-core bosons in a two-dimensional optical lattice subject to an effective magnetic field by employing the gauged CP$^1$ model.
