Computational Fluid Dynamics for Irregular Pentagon Natural Circulation Loop

IOP Conference Series: Materials Science and Engineering
Abstract Abstract. Electricity is an important needs for everyday life. Nuclear Reactor is a power plant that have low CO2 emission and the energy is available at any time. Nuclear reactor needs a passive safety system that allow it to run without external power source or any human intervention.

Extended Kelvin theorem in relativistic magnetohydrodynamics [PDF]

, 2000
We prove the existence of a generalization of Kelvin's circulation theorem in general relativity which is applicable to perfect isentropic magnetohydrodynamic flow. The argument is based on a new version of the Lagrangian for perfect magnetohydrodynamics.

ExoCubed: A Riemann-solver-based Cubed-sphere Dynamic Core for Planetary Atmospheres

The Astrophysical Journal
The computational fluid dynamics on a sphere is relevant to global simulations of geophysical fluid dynamics. Using the conventional spherical–polar (or lat–lon) grid results in a singularity at the poles, with orders-of-magnitude-smaller cell sizes at ...

A Laboratory Model of the Large-Scale Atmospheric Circulation of Tidally Locked Exoplanets

Atmosphere
We report on a novel fluid dynamics experiment configuration based on a modified version of the differentially heated rotating annulus, a widely used laboratory model of the large-scale mid-latitude atmospheric circulation.

The physical oceanography of the transport of floating marine debris

Environmental Research Letters, 2020
Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is unaccounted for.

The wake dynamics and flight forces of the fruit fly Drosophila melanogaster [PDF]

, 1996
We have used flow visualizations and instantaneous force measurements of tethered fruit flies (Drosophila melanogaster) to study the dynamics of force generation during flight.

Dynamics and Statistics of Reorientations of Large-Scale Circulation in Turbulent Rotating Rayleigh-B\'{e}nard Convection

, 2019
We present a direct numerical simulation to investigate the dynamics and statistics of reorientations of large-scale circulation (LSC) in turbulent rotating Rayleigh-B\'{e}nard convection (RRBC) for air ($Pr=0.7$) contained in a cylindrical cell with ...

Evaluating airflow dynamics in common vertical circulation spaces of a multi-floor apartment building for mitigating airborne infection risks: A CFD modeling study

Heliyon
As more people increasingly inhabit indoor spaces, the importance of interior environment design has grown significantly. The focus of this research is to assess the air flow and air change per hour (ACH) within common service vertical circulation spaces

Computational fluid dynamics models and congenital heart diseases

Frontiers in Pediatrics, 2013
Mathematical modelling is a powerful tool to investigate hemodynamics of the circulatory system. With improving imaging techniques and detailed clinical investigations, it is now possible to construct patient-specific models of reconstructive surgeries ...

Time Course of the Dynamics of Cerebrospinal Fluid Circulation in Hypertensive Intracerebral Hemorrhage

Neurologia medico-chirurgica, 1984
The dynamics of cerebrospinal fluid (CSF) circulation in 20 cases with hypertensive intracerebral hemorrhage was estimated with radioisotope cisternography (RIC) using In-111-DTPA. CT scan was performed simultaneously to observe the changes in the intracranial pathologies.
