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.
Simulation has long been used to improve the design of nearly every physical product or process by providing the opportunity to evaluate a wide range of alternative designs prior to building physical prototypes. Simulation has also long been used to model different operating scenarios to develop control strategies that are incorporated into control algorithms to improve operations.
Experimentation with aircraft in harsh environmental conditions can be difficult and expensive. The cost of materials, manufacturing limitations, physical limitations (size/temperature), and data gathering limitations are all issues that can be bypassed through the use of engineering simulation.
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..
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.
This worldwide leader in equipment for the hydropower industry validates, standardizes, and extends simulation as technical challenges increase. Each turbine has been optimized using fluid dynamics and checked with structural mechanics software from Ansys, a cost-efficient process.
By designing a tree-like wind power generator with steel branches and plastic leaves, New Wind has created an aesthetically pleasing alternative energy source for urban environments, bringing energy generation closer to people.
Analyze, visualize and communicate your simulation data with EnSight. Engineers use this powerful general purpose post-processing tool to gain new design insights and then clearly, effectively sell their recommendations. Flexible EnSight can read and visualize data from most simulation tools - Ansys and non-Ansys.
Energy & power industries demand products and processes with ever-increasing levels of safety, reliability, and regulatory compliance, and more operational capabilities, while lower costs and using fewer resources.
