A design approach for determining the optimal flow pattern in a landscape lake is proposed based on FLUENT simulation, multiple objective optimization, and parallel computing. This paper formulates the design into a multi-objective optimization problem, with lake circulation effects and operation cost as two objectives, and solves the optimization problem with non-dominated sorting genetic algorithm II. The lake flow pattern is modelled in FLUENT. The parallelization aims at multiple FLUENT instance runs, which is different from the FLUENT internal parallel solver. This approach: (1) proposes

A measurement of the angular velocity/revolution number of magnetically stirred liquid gallium-indium alloy was realized with newly developed angular velocity measuring equipment. To get additional information about the flow of the melt, a numerical simulation model was performed with ANSYS FLUENT 13.0 with a single phase 2D k-ε turbulence solver. The aim was to reproduce the flow as accurate as possible, so the measured and computed angular velocity data was compared, to see if the system can be modeled fairly well.

Also, supercavitation is studied at σ = 0.34 by the Zwart cavitation model. Reynolds-averaged Navier–Stokes (RANS) with the shear stress transport (SST) K-ω is employed as a turbulence model in transient analysis of Ansys FLUENT software. The numerical results show that, by increasing depth, the drag coefficient increases for both hydrofoils 1 and 2 as well as the lift coef

Abstract The aerodynamic properties of a vehicle are a factor in vehicle body development, such as the drag force, lift force, and flow pattern that occurs on the vehicle body. Using computational fluid dynamics (CFD), such as ANSYS Fluent, those properties can be investigated to design and analyze in many applications.

Comparison of the Aerodynamic Performance characteristics of NACA 2312 and NACA 2412 aerofoils under the same flow conditions at a Reynolds number of 2.74 x 106 is presented. ANSYS is used for the creation of geometry and meshing and FLUENT is used as a solver. Coefficient of lift and coefficient of drag for both aerofoils are compared for a range of Angle of Attack while the free stream velocity of air is kept constant. This analysis can be used for the wing design and other aerodynamic modelling corresponds to these aerofoils.

FLUX is a programming method for the design of agents that reason logically about their actions and sensor information in the presence of incomplete knowledge. The core of FLUX is a system of Constraint Handling Rules, which enables agents to maintain an internal model of their environment by which they control their own behavior. The general action representation formalism of the fluent calculus provides the formal semantics for the constraint solver. FLUX exhibits excellent computational behavior due to both a carefully restricted expressiveness and the inference paradigm of progression.

Application of the golf ball dimples on airfoils is predicted to be a good alternative for drag reduction. A golf ball with dimples allows for smooth and controlled flight. Models of cambered wings based on NACA 2412 airfoil were created to investigate the dimple effect. A comparative study is carried out between wing models with inward and outward dimples at 50% of chord length locations.

Results from this model were fed into the aeroacoustic solver, Actran, and used to calculate far field radiated noise as well as the directivity of that noise. The acoustic source of this noise was a plane wave of a known strength placed at the fan face. In addition to assessing the effects of mean flow on
