Detached Eddy Simulation (DES) of a Turbulent Premixed Flame Stabilized on a Bluff Body
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 2, June 2025.ABSTRACT As the demand for net‐zero emissions intensifies, low‐emission fuels (LEFs) are increasingly explored for their potential to reduce pollutants in combustion systems. The present study investigates the flame dynamics and pollutant emissions (CO and NOx) of different LEFs using detached eddy simulations (DES), a method that offers better ...

The New IEEE-754 Standard for Floating Point Arithmetic [PDF]
, 2008 The current IEEE-754 floating point standard was adopted 23 years ago. IEEE chartered a committee to revise the standard to include new common practice in floating point arithmetic, to incorporate decimal floating point into the standard, and to ...

Numerical Simulations of Forced Ignition and Flame Dynamics in an Ammonia/Air Mixing Layer
EnergiesThis work explores NH3/air non-premixed combustion in a mixing layer, with the objective of quantifying the influence of key parameters on ignition and flame dynamics. A series of two-dimensional simulations were conducted with forced ignition.
