Computational Fluid Dynamics (CFD) applications are “highly parallelizable” and can be distributed across a cluster of computers. However, because computation time can vary with the distributed part (mesh), the system loads are unpredictable and processors can have widely different computation speeds. Load balancing (and thus computational efficiency) across a heterogeneous cluster of processor...

This paper proposes an effective numerical methodology to analyze the mechanism of the separation of an inserted type of solid rocket booster from a supersonic air breathing engine vehicle having a conical intake. Unlike the previous computational fluid dynamic (CFD) approach, present work constructs a compacted model capable to reduce the computational time definitely. The dynamics of vehicle ...

Computational fluid dynamics (CFD) is a widely used numerical method for simulating complex systems, with applications ranging from aerodynamic science to hydrology. The latticeBoltzmann method is a relatively recent technique that has been shown to be as accurate as traditional CFD methods, but with the ability to integrate arbitrarily complex geometries at a reduced computational cost. Althou...

Air flow through electric fan heater channel is governed by coupled, non-linear partial differential equations; these equations have to be solved within on irregular domain subject to various initial and boundary conditions. Computational Fluid Dynamics (CFD) replaces fluid flow equations by a set of algebraic equations, these algebraic equations can be solved using digital computers. Wall to a...

Coupled blade element momentum-computational fluid dynamic (BEM-CFD) approaches have been extensively used to study tidal stream turbine performance and wake development. These shown be accurate when compared tests conducted in tow-tanks or regulated flumes with uniform flows across the turbine. Whilst such studies can very useful, it is questionable as what extent results would differ a larger...

The fluid mechanics principle is used extensively in designing axial flow fans and their associated equipment. This paper presents a computational fluid dynamics (CFD) modeling of air flow distribution from a radiator axial flow fan used in an acid pump truck Tier4 (APT T4) Repower. This axial flow fan augments the transfer of heat from the engine mounted on the APT T4. CFD analysis was perform...

Ink transfer process from the printing roll to the web was investigated using a Computational Fluid Dynamics (CFD) technique for the roll-to-roll (R2R) printing application. A parametric study was conducted to identify the effects of fluid parameters such as viscosity, surface tension and contact angle. To make the present analysis more relevant to the real printing system, a three-dimensional ...

The purpose of this work was to validate and apply a commercial computational fluid dynamics code with a hybrid RANS/LES turbulence computational model for a flow past a bluff body ultimately to help in the design of the caisson anchoring system during construction of a new adjacent span of the Tacoma Narrows Bridge. INTRODUCTION The new Tacoma Narrows Bridge will be designed as a suspension br...

The performance and hydrodynamic behavior of centrifugal pumps when handling two-phase liquid-liquid flow emulsion remain relatively unexplored, although they are fundamental importance in optimizing the operating conditions these pumps. Hence, this study aims at investigating degradation a pump under by combined means analytical computational fluid dynamic (CFD) models. approach is based on in...
