The simulation model of CFD software is established by taking the experienced parameters[3] µc =0.09, 1c =1.44, 2c =1.92, kσ =1.0, εσ =1.3

These results will be used for comparison with CFD calculations of flow around cooling towers in full scale.

The single-phase airflow is calculated using the commercial CFD package ANSYS-CFX 11.0 in the bearing chamber.
It is assumed that air exited the chamber through the scavenge is negligible and that the discharged air through the vent port only influences local air velocities in the vicinity of this vent, and thus these geometry features are omitted in the CFD calculation.
(a) (b) Fig.5 Variation of oil droplet velocities with the shaft speeds (a) without considering breakup, and (b) after breakup Conclusions Simulations of the single phase turbulent air flow and the oil droplet motion in an aeroengine bearing chamber have been carried out in order to assess the influence of the breakup on oil droplet motion for shaft speeds in the range 9,000 to 15,000 rpm.

The influence of cell shape, relative density and pore gases on the macroscopic honeycomb thermal properties is investigated by means of transient dynamic computational simulations.
The general purpose CFD package ANSYS CFX 11 was used for the time dependent thermal analysis.
According to these simulations the proper mesh size (l ≈ 0.09 mm) and time step (∆t = 0.1 s and ∆t = 0.01 s in case of considering the convection) were set.
For this purpose transient simulations considering heat conduction in the base material and pore gas have been performed.
The influence of the natural convection was analyzed with additional computational simulations.

Simulation is carried out for Reynolds number varies from 10 to100 for the fluid as air with Prandtl number as 0.71.
About 1,71,783Tetrahedran meshes are used for simulation and mesh near to cylinder is shown in Fig. 1(b).
It is observed that the present numerical simulation shows close agreement with them.
Simulations are carried out for Re = 10, 20, 30, 40, 100.

Key words: Numerical simulation, RNG k-ε turbulence model, Integrated Reactor Abstract.
A numerical simulation has been carried out to study the flow field in the two-phase integration of sludge thickening and digestion reactor.
The application of CFD simulations to tanks has also been reviewed by Placek, Tavlarides, Smith, and Fort [8], Kresta and Wood [9], Harris [10], and Vivaldo-Lima, Wood, and Penlidis [11].
The standard k-ε turbulence model that has been commonly used has some deficiencies when it is applied to the simulation of flow impingement and separation [12].

Code Verification Verifying mesh independence ensures that CFD results reflect the underlying physics rather than artifacts of grid discretization.
