Background
We offer a method to improve the passive scalar homogenization of mixing fluidic jets in cross flow configurations especially within the combustion chamber of a turbine. This is achieved by using fluidic oscillators that create an oscillating or pulsating fluid flow at the oscillator exit due to their way of construction. By this improved method high amounts of steam can be added to the combustion process and thus significantly increase the level of efficiency.

The oscillation frequency of the injected fuel is thereby regulated only by the mass feed of the supplied fluid.
The combination of cross flow injection and oscillation/pulsation of the fluid flow increases primarily the mixing ration of the two fluid flows within a combustion chamber (fluid & air) and moreover leads to a more effective burning.
The fluidic actuators can be installed within new (gas) turbines but can also be integrated in already existing ones.

Benefits:
  • Better temporal homogenization: NOx reduction, improved fuel value
  • Pressure loss in turbine is reduced: enhancing performance rate
  • Decrease of mixing length by ca. 50%: turbines could be build smaller
  • Fluidic oscillators require less maintenance
  • Usage of nearly any gaseous fuels
  • Increased macro- and micromixing phenomena: higher gains in mixing quality

The invention describes a simulation system and a simulation method for studying the operability of a vehicle by an operator. The method is characterized by a primary data set with a fixed predetermined resource profile for solving at least one primary task when operating a vehicle.

In this way an elaborate simulation of the primary task is avoided and enables an effective linkage with a secondary data set, which affects at least one secondary task, especially the usability of a infotainment system and / or dialogue system while operating the vehicle. The primary data set and secondary data set are transferred to a simulation and a function of primary and secondary data set automatically determines the influence of at least one primary task on the implementation of at least one secondary task. Thus the effect of infotainment systems and dialogue systems in vehicles can be easily examined.

Market Potential: Worldwide
Benefits:

 The major advantage of such model based analytical methods compared to “real” user tests lies in the shorter time that is necessary to evaluate and compare design alternatives in the development process. Thus the development process can incorporate many repetitive (virtual) tests that support later “real” user tests implementing quality checks.
