Force Prediction

Prediction of aerodynamic coefficients of objects is one of the classic applications of flow simulation. Besides the ability to simulate airflow over the entire range of engineering-relevant Reynolds numbers from laminar and transitional to subsonic, supersonic and even hypersonic flows, FloEFD offers a wide range of additional physical models for characterization of the aerodynamic behavior of a design.

Dimensioning of valves under a given cost, reliability and lifetime requirements is often a challenge for engineers, especially if fluids with complex properties or special physical effects are involved. To address this, FloEFD offers for example, a full two-phase implementation of steam for a very accurate virtual testing of devices with steam under various physical and environment conditions.

Analyzing upfront, potential wind loads on structures such as buildings, bridges, antennas, etc, are one of the major factors often defining the requirements for dimensioning and testing of those structures for stress, deformation, and dynamic response. In order to get realistic aerodynamic loads for subsequent structural analyses a simulation of various wind load conditions is essential.

Computed flow-induced loads using concurrent FloEFD, can easily be transferred to leading FEM structural analysis software either using ready-to-run FEM bridges such as Pro/ENGINEER Mechanica bridge, or by employing FloEFD's powerful Application Programming Interface to access and transfer FloEFD.

Automatic cleaning systems often employ specifically designed local flow patterns to generate the necessary level of near-wall shear stress for removing unwanted material accumulated at the wall, in gaps, etc.

Predicting torque as a fundamental reaction force to flow is very important for many designs such as the operation of valves (opening/closing) and the dimensioning of the corresponding drives, the torque acting on rotating parts such as impellers, and many more.
