RIGID AND FLEXIBLE BODY SIMULATION OF AN AIRCRAFT WING TEST RIG – APPLICATION BRIEF

Every airplane passenger who has ever sat next to the wing in rough air has surely noticed how much deflection it can undergo, and has likely hoped that the wing bending tests have been thoroughly performed! The truth is that these tests go far beyond what the passenger will ever see. Wing reliability under extreme loading conditions is tested with deflections of over 5 meters between the utmost downward and upward positions of the cycle. Similarly, the fuselage is pressurized during testing to levels that would never be encountered in normal operating conditions.

Cavitation: A Critical CFD App You Have to Get Right – Application Brief

Cavitation is the formation of vapor bubbles within a liquid when flow dynamics cause the local static pressure to drop below the vapor pressure. The bubbles usually last a short time, collapsing when they encounter higher pressure. Cavitation can cause noise and vibration, structural wear and damage, leading to reduced performance. It is a common problem in pumps (especially centrifugal or positive displacement pumps), compressors, hydraulic turbines, propellers, fuel injectors and other fluid devices subjected to high variations in pressure..

Overset Mesh Can Simplify and Speed Simulations with Moving Parts – Application Brief

A common difficulty in simulating complex fluid flow problems is that some geometries can not be well-represented using a single, contiguous mesh. In many cases, different geometrical features are best represented by different mesh types. Preparing this mesh can be time consuming and complicated. Additionally, the large, poorly structured meshes that result can take excessive time to solve and can result in reduced accuracy.

Turn Up the Heat in a Rooftop Heating Unit – Article – Ansys Advantage – V12 I1

In designing a new rooftop heating unit, AAON engineers needed to deliver higher airflow while maintaining the same footprint as an earlier design. The team used Ansys computational fluid dynamics (CFD) software to calculate airflow through the heat exchanger of the unit and iterate to a design that meets energy efficiency, airflow and heat transfer requirements. The use of simulation in this project saved 60 to 80 hours of physical lab work compared to traditional design methods.

Rotating Machinery: A Critical CFD App You Have to Get Right – Application Brief

In today’s globally competitive marketplace, it’s very difficult to imagine developing a competitive rotating machinery product without the benefit of simulation. Many rotating machinery companies were early adopters of simulation and played a significant role in shaping software development to their needs and validating it for their applications.
