Numerical simulation of convective airflow in an empty room [PDF]

, 2011
Numerical simulation of airflow inside an empty room has been carried out for a forced convection, a natural convection and a mixed convection respectively, by using a computational fluid dynamics approach of solving the Reynolds-averaged Navier-Stokes ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Effect of divergence on the compressible flow patterns in off-design planar nozzles [PDF]

FME Transactions
In the present work, the objective is to determine the Mach number and static pressure flow field behavior for off-design planar nozzle geometries with divergent angles of 1.21° (model A1) and 10.85° (model B1).

Investigation of hidden-charm pentaquarks with strangeness $$S=-1$$ S = - 1

European Physical Journal C: Particles and Fields, 2022
Recently, a new hidden-charm pentaquark state $$P_{cs}(4459)$$ P cs ( 4459 ) was reported by the LHCb Collaboration. Stimulated by the fact that all hidden-charm pentaquark states in $$S=0$$ S = 0 systems were successfully studied by the chiral quark ...

A fast direct numerical simulation method for characterising hydraulic roughness [PDF]

Journal of Fluid Mechanics, 2015
We describe a fast direct numerical simulation (DNS) method that promises to directly characterise the hydraulic roughness of any given rough surface, from the hydraulically smooth to the fully rough regime.

Proper Orthogonal Decomposition Closure Models For Turbulent Flows: A Numerical Comparison

, 2011
This paper puts forth two new closure models for the proper orthogonal decomposition reduced-order modeling of structurally dominated turbulent flows: the dynamic subgrid-scale model and the variational multiscale model.

An Adaptive Management Model for Brown Bears in Hokkaido: Based on Total Population and the Number of Nuisance Bears

Population Ecology, EarlyView.
Bear management changes management actions according to the horizontal axis of the population size and the vertical axis of the number of nuisance bears. Aiming for the target population size of Ntar, Actions I and II protect the bears, and Action IV reduces the population.
