Besides, many researchers analyzed the transient characteristics of liquid slosh numerically with CFD software.
The simulation and analysis method in this paper would be used in stability control of tank vehicles in the future.
To get suitable simulation speed and relatively higher simulation accuracy, the liquid equivalent dynamic slosh model is combined of both the steady-state model and the pendulum damping model.
The vehicle configurations used in the simulation are shown in Table 1.

Abstract.
In the study, the viscoelastic flow pattern of a commercial low density polyethylene (LDPE) extruded through out of the hollow profiled extrusion die is investigated by means of finite element simulation.
Numerical simulation as a highly effective method can well predict such complex phenomenon as in the polymer processing and hence to explain relevant mechanism.
However, viscoelastic flow simulation still remains a challenging task in Computational Fluid Dynamics (CFD).
The finite element simulation is thereafter conducted in the adjusted flow field and the process is repeated until the maximum coordinate difference between two iteration steps is less than the tolerance.

Beata Niezgoda-Żelasko et al. [7] simulated the momentum transfer characteristics of ice slurries in a horizontal pipe under the adiabatic condition via CFD.
Studies on the flow and heat transfer properties of ice slurries by simulations using Fluent have received only a little attention in the literatures.

In this respect, many researchers have done lots of work in the configuration design [1, 2], experimental study [1-4], CFD study [5-8], combustion liner wall temperature calculation using empirical correlations [3, 9-11], and optimization of film cooling airflow requirement [12, 13].
Through experimental studies and CFD simulation, they found that it is necessary to incorporate geometrical parameters such asin empirical correlations.
The CFD results show that the functional form is one of the best candidates for correlation.
