Tecplot helps utility researchers visualize magnetic fields

Case Studies, Civil Engineering, Energy, Tecplot 360 June 14, 2007

Contributed by Sylvain Gravel Hydro-Québec The Challenge: Accurately Visualizing Magnetic Flux Density In working with electrical power production and distribution, a key problem faced is being able to see the unseen – in other words, how does one view invisible electrical and magnetic forces at play? Hydro-Québec needed to be able to see magnetic flux density near a distribution power line, which is essentially understanding the power flow in the […]

Advanced Simulation Code Unveils the Mystery of Acoustic Waves

Acoustics, Case Studies, Tecplot 360 December 15, 2006

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 […]

NASA CFD Software Helps Quiet the Skies

Aerospace, Case Studies, Tecplot 360 March 16, 2003

Contributed by: Dr. Craig Hunter, NASA Langley Research Center Noise Sources in a Jet Plume The jet plume in Figure 1 originates from a bypass ratio (BPR) typical of a transport aircraft. Noise sources are shown in a 12,500 Hz frequency band (sub-scale) with the observer at 88 degrees to the inlet. The data set has about 35 variables at 17 million cells. The bypass ratio relates the size of […]

Plot of the month: Melbourne cricket ground redevelopment

Case Studies, Civil Engineering, Tecplot 360 July 12, 2002

Contributed by Eric Jal, Sr. Engineer, Energy Div. Connell Wagner, Melbourne, Australia Ventilation is a key design factor for the new Melbourne Cricket Ground (MCG). Using PHOENICS to optimize the design, CFD and Tecplot have been used to analyze air movement within the building and in external areas. In this image we see relative changes in air movement patterns across the pitch due to the construction of the new Northern […]
