In this paper, the heat transfer process of viscoelastic fluid in the microchannel is studied by numerical simulation method.
The simulation results show that the maximum heat transfer enhancement of viscoelastic fluid is up to 800%, compared with pure viscous fluid.
Their aim was to set a CFD model with FLUENT, and then compare it with analytical approaches.
Numerical simulation In this paper, the model of a micro rectangle pipe heated by electric heating was used in the numerical simulation of the heat transfer process.

This paper presents magnetic saturation analysis of non-parametric model of magnetorheological (MR) damper using ANSYS for improvement of the higher force with optimal current and MATLAB/Simulink simulation for quarter car model equipped with MR damper to conduct dynamic studies of the system using skyhook controller and comparative study for passive and semi-active system.
Parlak et al. (2012) studied the design optimization of magneto-rheological damper in order to get best result under given circumstances for magnetic flux density by using FEM, electromagnetic analysis of magnetic field and Computational Fluid Dynamics (CFD) analysis.
Fig.5 presents simulation results of damping force against velocity.
Simulation result shows that the quarter car model with semi-active suspension provides better performance over passive suspension system.

Almost all mainstream numerical method in CFD have been successfully applied in simulation of the free oscillation of liquid droplet, these include boundary element, finite difference, and finite element methods as well as integration of surface track /capture techniques such as MAC(Marker and Cell), VOF(Volume-of-Fluid), ALE (the Arbitrary Lagangian-Eulerian method) and level set methods.
To date, the literature on simulation of oscillation of non-Newtonian, e.g., viscolastic drops is quite sparse.
In this part, we compare with the results of linear analysis to validate our simulation.
It is shown that the agreement between the simulation and the linear theory is satisfactory; and that the present numerical simulations perform well for studying quantitatively the effect of material parameters on the droplet oscillations.
The results of numerical simulation and linear theory are identical.

Computational method In this study, a commercial computational fluid dynamic (CFD) package, Flow3D™ [6], was utilized to model the flow behavior of a glass sealant.
For simplifying the simulation model, one fourth of complete squared mold geometry is meshed by structured cubic grids.

Abstract.
For the simulation results presented here, the gap-dependent IHTC was used with an initial value of 2569 W/m2K (from Fig. 3 (left)).
CFD modelling (ProCAST in this case) was found to fairly successfully predict the air-gap, temperatures and the IHTC, enabling application of the model to situations where non-destructive techniques are required.

When the method of finite volumes is applied the CFD Fluent package [9] offers one more advantage, namely the possibility to deploy non-orthogonal and non-uniforms calculation grids, which is the matter of crucial importance when computation tasks are carried out for objects with sophisticated shapes.
The completed initial simulations enabled to find out that the inlet vortex for air gusts within a vertical plane may only appear for air velocities of Ma=0.005 when a<-10o as well as for Ma = 0.0075 and a = -5o.

However the spokes in a steel tower are thinner and therefore the impact will be smaller, this is to be quantified or simulated in a computer-flow-diagram (CFD) analysis.
According to the author, many locations have ‘a prevailing wind direction’ and therefore an oblique tower tip may be worth pursuing and CFD analysis will be able to show which improvement is possible for a SWiPP.

Additionally, numerical simulation emerges as an essential tool for understanding and optimizing these processes.
In this context, numerical simulation emerges as an essential tool, enabling a detailed analysis of heating during microwave drying of coffee beans [16,17].
This difference can be explained as the numerical simulation does not consider the mass transfer and moisture variation during the process.
