Hydro-Acoustic Simulation of a Hydraulic Hammer


CFD Simulation in a Stented Cerebral Aneurysm


CHB Internal Combustion Engine



In the swiftly growing offshore wind industry, sound emission especially under water is a growing concern. In order to determine the peak sound pressure at certain locations in advance a detailed numerical simulation of the transient driving impact and the related hydroacoustics is necessary.

Using the ANSYS® Workbench™ environment, a flexible dynamics model was set up to assess the underwater noise emission from hammer impact, through the pile and into the surrounding area.

Customer benefit:

High noise levels are easily assessed through this simulation. Hence appropriate noise protection systems can be developed such enclosing the pile in a “bubble curtain” or an auxiliary pile with air cambers, treatment of the pile surface or other solutions.

ANSYS IcemCFD supports the generation of very thin prism layers on the wall and it allows the accurate prediction of the wall shear stress distribution. The numerical simulations can be easily performed on a fine computational mesh using ANSYS Fluent on parallel computers in order to keep acceptable computing times.


The components depicted range from cylinder-liners to pistons. The cylinder-liners were analyzed using CFD -Fluent. Fluent has helped the company to minimize research and development costs dramatically, since problems in in-cylinder-cooling have been detected while the component has been flowing through our in-house workflow. These problems were then specifically defined and solutions were derived from further analysis using Fluent, CAE Software.

The pistons have been analyzed using ANSYS Mechanical, CAE Software. Structural and Thermal simulations play a vital role in our revolutionary internal combustion engine product line -the CHB-Engine Family- since most components are revolutionary in themselves, due to the proprietary materials being used to manufacture them. The pistons are manufactured from ceramic-like composite materials, which set an entirely new market tier, when compared with common aluminum alloy pistons. For that matter, the company has relied significantly and effectively on the Structural and Thermal CAE results derived from various analysis performed using ANSYS Mechanical, CAE Software.

The ANSYS CAE Software product pallet has aided NIAMA-REISSER, LLC to pass through certain development stages more rapidly and cost effectively. Our previous Thermal and Structural analysis have been conducted through the use of other CAE software which yielded less accurate or cost effective results. For that reason, NIAMA-REISSER, LLC is appreciative of the effort and service that ANSYS has portrayed in recent past.

High stress (red) in the coolant channel coating (and the resulting erosion) is the life-limiting issue for the reactor.  The ANSYS Multiphysics simulation helped explain the role of creep in "Mid-Passage" erosion seen experimentally in the 1970's.


Ninsight used ANSYS Multiphysics and CFX to successfully develop a mass customizable caravan. With the powerful built-in fluid-structure-interaction capabilities, Ninsight was able to optimize the safety of highly individual designs.
