An Introduction to the Rank-n Nonlinear Harmonic Method
Posted Thursday September 3 at 8:40am
The flow field in turbomachinery is dominated by inherently unsteady flow features such as blade-row interactions, blade vibration, inlet distortions, or high thermal gradients. Perturbations due to propulsion-airframe integration, aircraft maneuvers, crosswind, and temperature non-uniformities coming from the outlet of combustors are just a few of the many sources that can undermine the performance, stability, and durability of gas turbine engines.
NUMECA's Nonlinear Harmonic method (NLH) enables a better understanding of the propagation of flow non-uniformities into turbomachinery components by accurately and efficiently modeling turbomachinery configurations that are subject to periodic variations.
Reducing Boiler Emissions Through Shape Optimization
Posted Sunday August 30 at 4:19pm
Heat exchangers are widely used, e.g. in domestic boilers. During natural gas combustion, harmful CO and NOx emissions are formed and have to be minimized. The cooling intensity inside the heat exchanger has an opposing impact on the emissions. For NOx minimization, a quick and strong cooling trajectory is preferred while CO emissions are generally minimized by a slow cooling process.
Understanding Tractor Trailer Aerodynamics Using a Time Accurate Approach
Posted Thursday August 13 at 3:6pm
Pointwise has released the webinar, Understanding Tractor Trailer Aerodynamics Using a Time Accurate Approach, which shows how multi-block hybrid meshing techniques can improve mesh quality and concentrate mesh density in areas of interest.
In the United States, 70 percent of freight tonnage is transported by tractor trailers each year. Tractor trailers spend much of their time at highway speeds, resulting in 65 percent of their fuel consumption being used to overcome aerodynamic drag.

Fluid Dynamics Investigation of the Sonic Boom on a Supersonic Aircraft Concept
Posted Monday August 3 at 10:1am
The return to supersonic flight is amongst the hottest topics in aviation today, as several companies (Boom Supersonic and Aerion Supersonic, among others) are actively developing new supersonic commercial airliners targeted to enter in service in the coming years. In this context, a quiet flight over land is one of the major challenges to ensure the regulatory compliance of such airliners. Several research centers and companies are building demonstrators to show large sonic boom reductions with smarter designs of all the parts of the aircraft.
