Lattice gas automaton modelling of a vortex flow meter: Strouhal–Reynolds number dependence

Coexisting phases and lattice dependence of a cellular automaton model for traffic flow.

The Biham-Middleton-Levine traffic model is perhaps the simplest system exhibiting phase transitions and self-organization. Moreover, it is an underpinning to extensive modern studies of traffic flow. The general belief is that the system exhibits a sharp phase transition from freely flowing to fully jammed, as a function of initial density of cars. However, we discover intermediate stable phas...

Spontaneous Nucleation in a Reactive Lattice Gas Automaton

The Effect of Galilean Non-Invariance in Lattice Gas Automaton One-Dimensional Flow

In the simple case of one-dimension al flow between plate s, we show t he effect of Galil ean non-i nveriance of th e usual hexagonal lattice gas mode. Thi s effect leads to a distorted velocity profile when the velocity exceeds a value of 0.4. Higher-order corre ctions to the Navier-Stokes equa tions are considered in a discussion of th e num erical importance of th e distortion.

Effect of Surface Roughness on Vortex Length and Efficiency of Gas-oil Cyclones through CFD Modelling

Separation of suspended droplets in a fluid flow has been a great concern for scientists and technologists. In the current study, the effect of the surface roughness on flow field and the performance of a gas-oil cyclone is studied numerically. The droplets and the turbulent airflow inside the cyclone are considered to be the discrete and continuous phases respectively. The Reynolds stress mode...

Correcting a Coriolis Meter for Two Phase Oil & Gas Flow

It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...
