The energy model due to the compressible flow solver (density-based) is activated in this simulation. Due to the importance of the effects of the forces, including drag, on the body, the calculation of these forces is important, which can be calculated with the help of CFD.
The free fall test can also be performed in a tunnel to examine the effects of airflow on a falling object. The purpose of these experiments is usually to investigate the aerodynamic conditions and visibility of the flow lines.
Among the many experiments that can be performed in wind tunnels, we can mention the testing of various structures, including various types of airfoils, planes, static structures, etc. The wind tunnel is one of the most widely used aerodynamic testing devices today. The mesh type is unstructured and the total element number is 179542. Geometry is designed in ANSYS design modeler® and is meshed in ANSYS meshing®. This project aims to investigate the drag force on this body. In this project, a wind tunnel and a specific body that is placed inside it, are modeled by ANSYS Fluent software. Civil & Hydraulic Structures Engineering.In terms of both practicality and accuracy, co-simulation (in which both codes exchange data as they simultaneously run) is one way to tackle problems such as aerodynamic flutter, fluid induced bending, vortex induced vibration, and galloping. The coupling between STAR-CCM+ and Abaqus brings the solution of a wide range of FSI problems within reach. The options available in Abaqus are similarly broad, with coupled simulation supported for static stress/displacement, dynamics (implicit and explicit), heat transfer, temperature-displacement, thermal-electrical, and piezoelectric analysis. Point STAR-CCM+ at the Abaqus job you want to run and press “Go.” The physics of both codes may be leveraged in coupled FSI with STAR-CCM+’s full range of available models, providing the ability to study coupled, single and multiphase flows, chemical reaction, and combustion as well as flow regimes from low speed to hypersonic. This will make coupled fluid-structure-thermal calculations a regular part of the engineering design process.ĬD-adapco’s partnership with SIMULIA also means that setting up and running the problem may all be done within the STAR-CCM+ environment with no need for writing scripts and input files or mapping data. Using direct co-simulation coupling provides efficiency and reduced overhead associated with issues such as data transfer through file exchanges or use of external middleware software.
CD-adapco’s STAR-CCM+ will have a direct link to Abaqus FEA, delivering two-way fluid-structure interaction.
