An aerodynamic technique to calculating lift and drag coefficients is one of the required instruments in wing design process. During last decades, several tools software have been developed according aero-dynamics numerical methods. Nowadays, aeronautical architecture requires many calculations. Today’s techno-logists use a variety simulation techniques avoid expensive model testing. This paper...

The main goal of this study was comparing the performance an open-source code OpenFOAM and a commercial software Ansys Fluent in simulating turbulent flow through scour hole developed sand bed channel, which helps to give hint choosing appropriate calculating tool. Both models were set with same mesh as similar possible numerical settings, RANS turbulence modeling, applying k-?SST model, transi...

This paper presents the comparison of numerical simulation results and wind tunnel experiment for compound WIG's wing. Numerical was performed in ANSYS Fluent software. The choice turbulence model computational mesh parameters, including resolution boundary layer, are substantiated. Comparison showed good convergence middle density about 7 million cells first layer height 0.0001 m. Additional s...

An investigation on enhancement of heat transfer is carried out for a double pipe exchanger in which the outer wall inner provided with circumferential labyrinth passages. Rectangular and triangular cavities fixed tooth thickness, height, pitch are considered effect added structures characteristics discussed. A two-dimensional steady numerical simulation using ANSYS-FLUENT software. The flow Re...

Computational Fluid Dynamics (CFD) is a computer-based tool for simulating fluid movement. The main advantages of CFD over other fluid mechanics studies include: substantial savings in time and cost, the analysis of systems or conditions that are very difficult to simulate experimentally (as is the case of the airways), and a practically unlimited level of detail. We used the Ansys-Fluent CFD p...

The performance of two commercial simulation codes, Ansys Fluent and Comsol Multiphysics, is thoroughly examined for a recently established two-phase flow benchmark test case. In addition, the commercial codes are directly compared with the newly developed academic code, FeatFlow TP2D. The results from this study show that the commercial codes fail to converge and produce accurate results, and ...

The modern development in mathematics bridges this gap (see Fig. 1). It allows us to start from a high dimensional system obtained by finite elements and then automatically generate a low dimensional approximation. The dimension of a reduced model is controlled by the approximation error specified by the user. In this article the software MOR for ANSYS [1] is presented. MOR for ANSYS applies ne...

ABSTRACT: This paper describes analysis of deep beams subjected to two point loading with three different L/D ratios (1.5, 1.6, 1.71) using Non-linear Finite element method (ANSYS 9.0 software) in order to investigate the stress and strain distribution pattern at mid-section of the beam. In ANSYS 9.0 software, SOLID 65 and LINK 8 element represent concrete and reinforcing steel bars. Non-linear...

Data are related to the numerical simulation performed in the study entitled "CFD modeling to evaluate the thermal performances of window frames in accordance with the ISO 10077" (Malvoni et al., 2016) [1]. The paper focuses on the results from a two-dimensional numerical analysis for ten frame sections suggested by the ISO 10077-2 and performed using GAMBIT 2.2 and ANSYS FLUENT 14.5 CFD code. ...

The objective of the present paper is a numerical analysis of the flow forces acting on spool surfaces of a pressure regulated valve. The transient, compressible and turbulent flow structures inside the valve are simulated using ANSYS FLUENT coupled with a special UDF. Here, valve inlet pressure is varied in a stepwise manner. For every value of inlet pressure, transient analysis leads to a qua...
