Tecplot’s SZL Server, a Client-Server Solution for Visual Analysis of Remote Data

Chris Nelson is the Chief Scientist for CFD at Innovative Technology Applications Company, LLC. Recently, one of his focuses has been on solving complex problems in jet noise simulation. The Challenge Chris runs his CFD cases on the ITAC computer in Missouri and a host of other remote high performance computing (HPC) systems. The jet noise simulations were mostly run on DOD HPC systems. He generally works from home, so […]

Predicting broadband noise in wind turbines

Innovative Technology Applications Company, LLC using numerical simulation to examine the flow around wind turbines and accurately identify the acoustic field sources that are associated with the unsteady fluid behavior. In 2010, global wind power installations increased by 22%, according to the most recent information available from the Global Wind Energy Council (GWEC), an international representative forum for the wind energy sector. This added capacity represents investments worth $65 billion, […]

Using Visualization for Faster Understanding of Noise Issues

Contributed by Shen Heping, Software Development Manager, Hong Yuan Tech. Cars that ride more quietly. Higher-quality acoustics in auditoriums. Aircraft that meet or noise pollution regulations. These are just a few examples of how scientists and engineers can develop more comfortable, enjoyable, or environmentally-sound products by studying the source and distribution of noise. The ability to actually see the noise distribution or what’s going on around the noise source helps […]

Advanced Simulation Code Unveils the Mystery of Acoustic Waves

Contributed by Dr. Baki Farouk Drexel University Problem Statement: Numerical simulations of the standing wave and acoustic streaming in a resonator filled with nitrogen (Fig. 1) are presented. The initial gas pressure in the resonator is 1 atm (101 KPa), and temperature is 300 K. The vibrational frequency of the left wall is chosen as f = 20 kHz. The corresponding wavelength of the sound wave at this frequency is […]
