The full flow field model of a widely used multi-blade centrifugal was built, using the CFD method, the steady and unsteady numerical simulation of the inner flow in the fan at different working conditions are presented.
The numerical simulation results were validated by contrasting to the experiment results.
The quality of the grids is one of the key factors determining performance of numerical simulation [3].
In order to make sure the stability of the unsteady simulation, the steady numerical simulation is done at first based on the same mesh subdivision, after that, the results of the steady simulation are used as the beginning field to proceed with the whole passage unsteady simulation inside the multi-blade centrifugal fan.

In their work, simulations have been done for different flow configurations and separation only vs. reactive cases.
The numerical simulations were based on the CFD method devised by Coroneo et al. [5, 6] which was developed in the realm of a finite volume CFD code but in this case, O2 is separated from air instead of H2 separation in their case.
The general-purpose commercial CFD code Fluent 6.3 was selected for the solution of the steady-state conservation equations adopting either the laminar or the turbulent formulation depending on the specific flow regime.
Despite the largest partial pressure differences relative to all other ITM simulations, the flux remains relatively low until the end of the reactor.

The FEA is to simulate conduction in solids, and the CFD could be used to simulate both conduction and convection.
The modified thermal parameters are determined by correlation between CFD and FEA of simple geometries [19].
Meanwhile, CFD will be used as a supplement to determine heat transfer coefficients and conductivities for FEA, and sometimes to be the only way for simulations of highly flow dependent problems, such as the flow control module (FCM) with strong free convection.
The important key data required for the thermal analysis [7,9] based on the methods of FEA and CFD are listed below.
Additionally, FEA and CFD are two feasible methods for thermal analysis.

The ultimate aim of this paper is to develop a validated CFD model to predict the extent of particle agglomeration within a spray dryer, and the flow patterns and drying of particles, and to use this predictive tool to design more efficient spray dryers that produce higher throughputs.
Methods It is the aim of the author to address this gap in fundamental understanding and to develop a Computational Fluid Dynamics (CFD) model to predict the turbulent dispersion and coalescence of droplets within a spray.
A commercially-available Computational Fluid Dynamic (CFD) program called ANSYS CFX4 is used to solve the equation sets for the Eulerian and Lagrangian approaches described above.
All subsequent simulations involving different droplet flows, gas flows or droplet size distributions adopt the same values for these parameters.

The paper is devoted to selection of a numerical approach for simulation of fluid flow in a torque flow pump of “Turo” type and its influence on simulation results.
At present numerical simulation of fluid flow in pumps is used with modern CFD-codes.
Numerical simulation allows costs decrease in dozen times.
However CFD-codes turbulence models and specified initial conditions, used for centrifugal pumps, don’t show adequate flow pattern for vortex pumps because of their flow structure differences.
