A numerical simulation of the effect evaluation heat loss and temperature distribution along wellbore is performed, for two models, first an open hole (without perforation) other a perforated vertical wellbore. In this study, Computational Fluid Dynamics (CFD) software code ANSYS FLUENT 15.0 has been used, simulate model 3-D turbulent flow with stander k-ϵ model. The results show that, increasi...

The fluid/structure interaction (FSI) investigations of stacked chip in encapsulation process of moulded underfill packaging using the two-way Coupling method with ANSYS Fluent and ANSYS Structural solvers are presented. The FSI study is executed with different aspect ratio of stacked chip on the mould filling during the encapsulation process. The simulation results in the FSI study is well val...

CFD (Computational Fluid Dynamics) simulations appear to be strong competitor of the wind tunnel test which required scaled model and it is really expensive and time consuming tool in designing bridges therefore there is a strong claim to replace them with CFD. Analyses carried out for different deck cross sections by secondary development of commercial computational fluid dynamics software ANS...

The recent advent of microelectromechanical systems (MEMS) or micro-devices has generated excitement in many diverse fields. In the area of micro-fluidics liquid pumps are highly desirable for fluid transport and atomization. A recent and popular example of this is the inkjet, which self-aspirates ink from a reservoir and then transports it to a chamber for expulsion as a single droplet during ...

Thermal jet flows are the type of flow frequently encountered in engineering applications. This article aims to determine if SST k-ω turbulence model, including Low-Reynold Correction, accurately estimates Nusselt number impinging flow; because this, computational results were compared with experimental studies. comparison was made on a line (r/D) from stagnation point exit. In this article, he...

Prevailing high-speed air-breathing propulsion systems invariably banks on coaxial jets which plays a vigorous role in stabilization of flames and combustion emission. Coaxial jets have applications in supersonic ejectors, noise control techniques and enhancement of mixing. Coaxial jet nozzles regulate spreading rates by developing virtuous mean flow and shortening primary flow potential core l...
