Nonideal particle distributions from kinetic freeze-out models [PDF]

open access: yes, 1998
In fluid dynamical models the freeze-out of particles across a three-dimensional space-time hypersurface is discussed. The calculation of final momentum distribution of emitted particles is described for freeze-out surfaces, with both spacelike and ...

Study on wellbore temperature of riserless mud recovery system by CFD approach and numerical calculation

open access: yesPetroleum, 2020
The riserless mud recovery (RMR) system abandons the riser used in conventional offshore drilling, and the drill string above the seabed is directly exposed to seawater, resulting in convective heat transfer from the drilling fluid in the drill string to

A drilling wellbore pressure calculation model considering the effect of gas dissolution and suspension

open access: yesFrontiers in Earth Science, 2022
The complex formation pressure system and diverse formation fluid components during deepwater and deep drilling make it easy for gas intrusion accidents to occur. The dissolution and suspension of the intruded gas in the drilling fluid and the difference

On the estimation of swimming and flying forces from wake measurements [PDF]

open access: yes, 2005
The transfer of momentum from an animal to fluid in its wake is fundamental to many swimming and flying modes of locomotion. Hence, properties of the wake are commonly studied in experiments to infer the magnitude and direction of locomotive forces ...

Fluid-Structure Interaction Simulation of a Coriolis Mass Flowmeter using a Lattice Boltzmann Method [PDF]

open access: yes, 2020
In this paper we use a fluid-structure interaction (FSI) approach to simulate a Coriolis mass flowmeter (CMF). The fluid dynamics are calculated by the open source framework OpenLB, based on the lattice Boltzmann method (LBM). For the structural dynamics
