Good Agreement

Abstract The present work assesses the capabilities of a compact skeletal mechanism, derived using an in-house reduction code, to accurately model chemical processes in a turbulent CH4/H2/N2 flame. To this end, a numerical investigation of the DLR-A flame is performed using the free and open-source code openfoam with the derived mechanism. Specifically, the numerical investigation is performed using the Reynolds-averaged Navier–Stokes (RANS) approach and a compact skeletal mechanism consisting of 51 elementary reactions among 21 species. The skeletal mechanism is derived from the GRI3.0 mechanism using an improved multistage reduction method. The k − ɛ model is used as a closure for the RANS equations, while the source terms in the species and energy transport equations are closed by the partially stirred reactor (PaSR) model. The radiation term is modeled by the P-1 model. The numerical results show a good agreement with the experimental data.

Underlying Assumption

Abstract We question Baumard's underlying assumption that humans have a propensity to innovate. Affordable transportation and energy underpinned the Industrial Revolution, making mass production/consumption possible. Although we cannot accept Baumard's thesis on the Industrial Revolution, it may help explain why complexity and innovation increase rapidly in the context of abundant energy.
